Modeller only uses internal coordinates for the restraints, so is independent of the relative orientations of your templates, but your initial model (.ini file) is probably bad to start with. One solution would be to manually translate one monomer in the .ini file so they don't overlap, and then provide that as your starting model.

This sounds like a problem with your alignment (most likely the "bad" chain isn't aligned with any template), but I'd need to see the real alignment file to be sure.
