Hi Jim,

Thank you for your reply. I am removing page breaks and replacing them with section breaks both for page numbering purposes and for the purposes of creating a specific kind of div in the HTML when saved as HTML (the book will be both print and eBook). I've done this for years, in hundreds of books, and have never run into a problem with it before. I've attached a marked-up screenshot. When the cursor is on the page before the shown section break, it says page 55. When I move it to the next page, it says page 57, and the mirror margins reflect this. There are zero additional section breaks later in the document (but there are page breaks, which I haven't removed yet). There are 25 of them earlier in the document, both "Next" and "Odd".

Does this help clarify the weird issue I'm running into?
