My moon animator animations look weird in the default animator or in the actual game

The animations I upload from Moon Animator deform and look weird ingame or in the default animator, and if I upload an animation on the default animator then import it into moon it looks really weird on moon. What is the problem?

Here’s what it looks like on moon animator (Where I animated the idle in the first place):

And here’s what it looks like on the default animator after I import it being originally animated on moon:

By the way the rig I’m using is a basic character but sized to be bigger than a normal one
