I was working with something later in a later flow of this piece. I got ready to print in the first page looks completely different. The second picture is what it used to look like. The first picture is what it now looks like. What do I have to do to fix this?
Hard to tell from pictures alone. Did you select the same layout in Print mode as you were viewing in Write/Engrave? Can you upload the actual Dorico file? It may be easier to find out.
It means that you edited a page directly instead of the page template. So that it’s not following the page template anymore. right-click the page and remove overrides. Not sure the result is what you want, but worth a try.
If you’re not going to use the composer/lyricist field on the first page, you could remove those text frames from the first page template, and raise the music frame. That would give you some more space to fit an additional flow.
