A page disappears in a Writer document but pops up in PDF

[sehrguey]

hi there
editing Hyperlink in a document under Headings, Target in Document reads '|outline'. When exported to PDF this '|outline' becomes an oddball line in the Content. Is there any way to get rid of it?
Besides, the .odt document file doesn't have the page linked to in the Content because in the document itself 'page 8' is directly followed by 'page 10', 'page 9' appears only if I delete the manual break after 'page 8' but I need that break.
it's Writer Version: 6.1.5.2 on debian 10
