Page numbers showing partially
Hello,
My InDesign book file of near 500 pages is absolutely ready for printing. On some pages though, the page numbers are disappearing or showing only partially, - in the program or after exporting the pdf file. They are all A-Master pages and are not layered because the book is without anything else than text.
I would be sincerely grateful for suggestions on how to fix that problem, as the print house is waiting for the file in the next days.
Below I am attaching screenshots.
