I have a very large (approx 700 pages) document that has been split into multiple sections with section breaks. Each Section has page numbers set up as Page Number of Section Numbers (each section starts back at 1).

I am finding that on the last page of some sections (ones that don’t have any more than four lines) the last page number says Page 2 of 8 (or however many pages are in that section) but as soon as the page has 5 lines on it the page/section numbers are fine.
