I run Finale 25 under Windows 10.

I am working on a 24 page score from an imported xml file. I find that page 7 for some reason is not formated properly so I deleted the imported pages from there to the end keeping the first six pages which were correct. I did this because just deleting page 7 moved the incorrect format to the next page - page 8. My plan was to add correctly formatted empty bars matching page 7 and then copy or rewrite that page, however, adding gave me a new and incorrect format - not the format of the preceeding six pages! How do I add measures to the end of a score in the same format used up to that point?
