Stuck on idle facial expression

[comet]

Hello, I'm having some serious issues with avatars 3.0 and so far, my expressions parameter works perfectly in unity but not at all when actually in vrchat

So far, my expressions wont change at all. Also while testing i noticed that if i change my expression from f# (any number) back to f1, it'll twitch as if reverting back from the expression that was supposed to be in f# to the idle once more, except just pressing f# changed nothing at all before. This leads me to believe that it's because the idle is overlapping the f# expression but i don't understand where how or why.

I know the doc says "don't use Write Defaults", but honestly i tried the other way of adding a revert layer and it didnt work either, plus everyone else uses Write Defaults, so I tried that too, but same result, so I'm pretty sure that's not the issue. Can someone help me?
