ANother Problem with importing animations

Hi everyone,

I am quite new to Blender and Unreal, so this might be a dumb question.

Basically, I made animatiosn for my model on Blender, but when I improt them on Unreal, they are broken. Parts are not going where they should. What am I doing wrong? I included my Blender file. Sorry, this is a filebin link, because new users apparently can’t uplaod files to the forum
