Eyes not closing after doing an animation

i’m having a problem with this avatars animation, where the eyes will stay shut after doing an animation, i’ve looked around and this issue could be caused by write defaults not being on, though it is and everything else should be fine, if anyone knows whats wrong feel free to ask anything.

i’ve found out that its not only the eyes, but the intire expression, i think its something about it not resetting the expression when its not activated

what does the animation tree look like?

Are you using VrcATC (Vrc Avatar Tracking Control)?
