Hi Philippetdev,
It looks like you are using library overrides for linking – is that the case?
At the moment, that method is EXTREMELY buggy and it isn’t possible to actually animate/change all the things you want to animate. So it’s best to stick with proxies until they actually make it work.
With the actions, if you want to edit them, make sure they are local to the file rather than linked in.
Hope that helps.
