Viewmodel Animations not running as intended?

Hey, i'm remaking my FPS Framework with new rigs and instead of creating CFrame animations, i use regular animations. I've noticed that the arm's (which are rigged correctly) don't play animations when a animation is loaded and played.

I also used print(anim1.IsPlaying)and it returned as true.

Here is some images to help.

Proof that the animation works in Moon Animation Suite: https://cdn.discordapp.com/attachments/610196793522913301/618129464454283268/unknown.png
