Link between score text and parts

Hi

I think I must have changed the title in one of my parts. Now changing the title of the Score no longer updates this part (but does for other parts). I can't see anything in the Inspector that differentiates them: is there a setting somewhere else? I.e. can I reestablish this link between part (title or any other text?) and score without re-generating the part? I'd rather not do all the little edits again.

Thanks
