The issue appears to be correlated to whether or not you have selected the Master of Imbuement Core Capstone. Read the thread for further details. A Bug Report template has been posted at the bottom of this post.
The purpose of this thread is to document the various Arcane Archer Imbue Toggles which are not working properly so that others and I can narrow down exactly what is happening which is bugging these abilities so that we can make effective and precise bug reports. So please report your issues with Arcane Archer Imbue Toggles here!
At the present moment, I have noticed the following Arcane Archer Imbue Toggles are bugged: Force Arrows, Fire Arrows, Corrosive Arrows, Frost Arrows, and Shock Arrows. When activating these toggles, they seem to be dismissed approximately 30 seconds after attacking. Now, I am aware that switching between Imbue Toggles is supposed to allow the previous Imbue Toggle to linger for 30 seconds. But that is not the issue. Without switching between Imbue Toggles at all, these Imbue Toggles seem to disappear from the buff bar as well as disappearing functionally (so this is not just a display bug). I suspect this ability is tied to the Arcane Archer enhancement which allows an Imbue Toggle to persist for 30 seconds after changing to a new Imbue Toggle, but I have not tested this issue without this enhancement so I cannot say for certain.
A very simple way to reproduce this issue and immediately notice its effect is to turn on Force Arrows then attack an incorporeal creature, such as a wraith or shadow; this works best while soloing without a hireling, summon, or pet so that you know the attack feedback is your own. As soon as you begin attacking the incorporeal creature, begin counting down to 30. After about 30 seconds you will notice that the "Incorporeal" feedback from attacking is appearing (seems to work well with shadows from Wheloon since they appear to have a higher incorporeal miss chance than other incorporeal creatures in the game) and that the Force Arrows buff is gone. However, the Force Arrows Imbue Toggle will still appear "On" on your hot bar (i. e. surrounded by the swirling blue line).
The following Imbue Toggles do not seem to have this issue: Smiting Arrows, Banishing Arrows, Paralyzing Arrows, Terror Arrows. Perhaps these Imbue Toggles are coded differently or perhaps I simply haven't noticed it with them. Also, this behavior does not seem to occur with Secondary Toggles: Metalline Arrows, Morphic Arrows, Shadow Arrows, and Morphic Arrows.
Please help me fill in the gaps if you have noticed strange behavior with the Imbue Toggles and under what conditions you have noticed this behavior. I have already bug-reported what I have noticed, but I feel my bug report was incomplete because I cannot tell exactly what it is that causes the Imbue Toggle buffs to be dismissed. So far, the only correlation I have found is attacking an enemy, but it is not always exactly 30 seconds so there might be something else causing the behavior.

Summary: Master of Imbuement Applies 30 Second Timer to Primary Toggles Even When They Are ON
Details: Master of Imbuement, the Arcane Archer Core Capstone, breaks primary toggles (Force Arrows, Elemental Arrows, Terror Arrows, Paralyzing Arrows, Smiting Arrows, and Banishing Arrows) by applying a 30 second timer even when the primary toggle is active. As per the description of Master of Imbuement, "When you leave a primary Arcane Archer Imbue stance, the bonus granted by the stance lingers for 30 seconds before being removed."
However, what actually occurs is that even if the stance is active, the 30 second timer starts anyway. Notably, this only seems to apply in private instances, such as quests and wilderness areas.
To reproduce this bug, do the following:
1) Create a 20th level ranger or 25th level elf or half-elf with access to the Arcane Archer enhancement tree.
2) Select any primary toggle (Force Arrows, Elemental Arrows, Terror Arrows, Paralyzing Arrows, Smiting Arrows, and Banishing Arrows) from the Arcane Archer tree and spend enough points to access the Master of Imbuement core capstone also.
3) Toggle on any primary toggle.
4) Enter a private instance (quest or wilderness area).
5) Note that 30 seconds after entering the instance the primary toggle will disappear from the buff bar and the effect will no longer apply to attacks, even though the toggle appears ON on the hot bar.
6) Reproduce a similar character but WITHOUT the Master of Imbuement enhancement.
7) Set any primary toggle to ON.
8) Enter a private instance.
9) Note that the primary toggle will remain on the buff bar and remain active for as long as the toggle is ON.
Quirks: Sometimes this issue may require being logged in for a certain amount of time before it presents itself. This time may or may not vary but has been reported to be in the area of 30 minutes on occasion. It may also be tied to the number of times you switch instances or whether or not you have switched characters recently on the same login period. Some primary toggles seem less prone to being affected. Smiting arrows and Banishing arrows are less commonly affected by this bug and may not be subject to it at all under certain conditions which have yet to be determined.
