I’m creating a Title page for my instrumental parts. Insert Page Before page 1, and assign my “Title Page” Master. So far, so good.
The trouble is that some (but not all) of the parts show Page 1 with a little red triangle, which means that changes to the Master don’t get applied to those pages. If I Remove Page Overrides, the Blank page gets deleted, and I’m back with music on Page 1 (First master).
The other parts show Page 1 as Title page, with a green bar and no red triangle. These parts will update to changes in the Title master. I can’t tell what I’m doing differently to get two different behaviours.
