I also experienced this frustrating problem. Even when you use Styles and
Formatting (Format) and set the First Page, followed by Default pages and
then input the headers on each page. You can save it and it is OK but once
you close it and open it again it has not held your save. And the
Why is it that Writer doesn't display header information for documents it saves
in MS Word format? Obviously the header information is still present (not lost
during the save) if the header information appears intact when re-opened using
Word.
I've tried to re-create your issue but cannot.
