Animations acting strange

You can write your topic however you want, but you need to answer these questions:

  1. What do you want to achieve? Keep it simple and clear!
    I want this animation to act normal
  2. What is the issue? Include screenshots / videos if possible!
    This animation is not acting normal

the animation should look like this

but it looks like this

I also have a script that edits the waist.C0

Did you tried looping the animation? Or changing the priorities?
