Idle Animation not working correctly

Hello! So I recently did a commission for 6 animations, one of them is not working some reason. When all the others do. It is called “Idle Animation”. I already tried fixing it several times, but it can’t seem to work.

It’s supposed to just swing it’s arms against its side which it does in animation editor but not in the npc mode.

Is there a way to fix this?

I can’t see the video try to upload the video on the forum or YouTube. but it seems more of a scripting problem to load the animation.

Are you using a humanoid with your npc?

Yes, I am using a humanoid with the npc.
