I seem to have bungled something due to not having understood master pages when I started my present project months ago. At that time, I created a custom score for use as a vocal score, and have been working on that score until now, when I need to orchestrate in the full score. I noticed that the odd-number page numbers on the full score were too far to the left, so I changed them in (what I thought was) the full score master page - but that made them disappear completely in the custom (vocal) score. Evidently these are linked, and I have been working with a master page set in the wrong way all this time.
I moved my page numbers back into the correct place for the vocal score, no problem, as I don’t want to lose the formatting of that score. However, I need the full score to look correct too. Is there a way to do this without impairing the custom score layout?
