Assets Tearing Apart in Composite Shot

Hello. So I'm making a walking cycle animation and it requires separated body parts. I already set the anchor points on each body parts to its joints. I managed to create a walking animation but it's not on loop, so I duplicated the keyframed layers. I duplicated it for 5 times. The problem is the more I duplicated those layers the more the body parts are tearing apart from it's joints. Does anyone know what's my problem is? Thank you.

(This is how it's duplicated)
