I’m on 2.11 under Windows. I’m unable to override the general header/footer on a single page using the Format->page dialog.
Steps to reproduce the problem:
Have a document style generic, plain theme. Set header/footers via Document->Page->Headers and set ‘page-rendering’ to ‘paper’ so that headers/footers show on screen. On a certain page, choose Format->page and change header/footers from ‘unchanged’ to something else. Close the dialog. On the page the old header/footer is displayed unchanged. When re-opening the dialog the new header/footer text is not there and ‘unchanged’ is shown instead.
Any idea what I’m doing wrong? Any help is appreciated.
