Locked part in moon animator

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!
    Animating a sword

  2. What is the issue? Include screenshots / videos if possible!
    One part in moon animator is locked and doesnt move, instead move the other parts for some reason

  3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
    Ive tried looking in Youtube and the devforums but no one seems to have the same problem

Can anyone help?
