I entered page numbers in a score in the usual way from pages 2 to 0 (end). Finale shows page numbers from page 2 to 9, then 10 pages with the number 1, 10 pages with the number 2 and 7 pages with the number 3 (until end). Weird. What's happening?

The score has 2 staff systems per page (A4). Before I started entering page numbers all staff systems were locked. I entered page numbers after unlocking all systems. Could that have something to do with it?
Thanks for any replies!
