My Animation Montage Won't Save?

I’ve got an animation montage working just fine. It works when I use it in blueprints and I am able to use it in-game. The problem is, as soon as I save Unreal Engine, exit, and load the project again, the animation resets to a default pose. Below is an image of it working properly and another image of showing it when it is loaded again. Please help!

Hi there, i have the exact same issue, did you find a solution for this?
Thanks already
