Page numbers shown in header become inaccurate after some time editing a document. For example, instead of starting with 1 the document will start with 0. Or a page number is repeated two pages in a row.
Closing and re-opening a file (and/or restarting LibreOffice) fixes the problem temporarily until it occurs again.
Could you please give more information how we can reproduce such a file or do you already have a sample file? Thank you very much in advance.
With a new file only with the page number in the header I could unfortunately not yet reproduce it (tested with LO 126.96.36.199, Win 8.1).
Please feel free to reopen with the info required.
