How should I copy/paste an Unwrap UVW modifier?

Hi there!

This is my first post on a forum so I'm not sure how it works.

I'm experiencing some trouble with a statue with four arms I'm modeling.

I modeled one arm and made 3 copies in the positions required and, while I mapped and texturized one arm, a partner was rigging and modeling it, so now we have one arm mapped, and four arms rigged and animated.

The problem I'm experiencing is that, when I copy the Unwrap modifier to the other arms (I've tried copy/paste and saving the channel and loading it on the other arms) the edges on some of the uv shells get assigned to different edges, deforming completely the textures.

How can I fix this?This is the mapped arm, the edges are assigned correctlyThis is the exact same uv channel on another arm, the same edges on the uv shell are assigned to different edges on the model
