If it's in the log, it's in the scoring function, so it's not being ignored. And your code looks fine to me. But you probably still have conflicting restraints, derived from the alignment. The usual way to resolve that is to tweak the alignment some more (one option would be to use multiple templates, one for each domain, to allow them to move relative to each other). You already said your helix is in a non-aligned region, but likely it's being affected by other aligned parts of the sequence.
