Hi! Try updating the meshes with the most current version and let me know if you still have the same problem. I've checked the source project and could not see the problem you're having, so there's a chance you're using an older version where this problem existed. I remember that I've fixed this issue a while back for some of the parts, but it could be that I've missed it in one of them. If problem persists, then please double check if the names of the meshes are correct, to make sure I'm looking at the right parts. Please keep me posted!
