I have a document which does not appear in "recent", strange and annoying

After recent updates, on Linux Mint 19 (updated), a document I use every morning has stopped appearing on “recent”. Is there anything I can do? (other documents appear kind of normally).
Thanks!

It doesn’t reappear even if you start it once using File -> Open?

No, I just tried after your suggestion.

Hmm …

  • is it saved in a different format (e.g. .docx) or anything else what it differentiates from other documents?
  • Have you already tried to reset your LibreOffice user profile?

No sir, it is saved as a very regular .odt file. It used to appear on the recent list until this winter.
No, I have not tried that. could it be related? Should I try it now?

Yes - test resetting your LibreOffice user profile

To reset the user profile perform:

  • Start LibreOffice
  • Start in Safe Mode using Help -> Restart in Safe Mode and confirm the restart using button: Restart
  • Archive your profile expanding Advanced (click on the word Advanced right above Help button) and click Archive User Profile button
  • Select option Reset to factory settings
  • Activate [x] Reset entire user profile
  • Click button Apply Changes and Restart


Would it be possible to upload the file (it could be sufficient to just upload the file without any content/text)?
