I may have stumbled into a bug on LibreOffice Writer (v 220.127.116.11 (x64), Windows). I had record track changes turned on as I edited and made comments on a document (saved in Word, docx (2007-365) format). I added comments, saved document, and closed it.
Later I opened it back up* to finish working on it and decided to delete a comment. When I did so, instead of than the comment deleting, an “X” was placed through the comment, it didn’t just delete or go away. I saved and re-opened thinking it would be gone but the comment was still there and fully restored (without the “X” through it and fully editable along with the option to delete the comment again - which would also result the X and ‘incomplete’ deletion).
I tried ‘deleting’ the comment again, got the X through it and then decided to try to delete the comment’s text but got an error that it was “Read Only Content” and “Write-protected content cannot be changed.”
I realized that somehow the the comments are becoming part of the ‘track changes’ tracking. I turned off the record track changes and then deleted the comment and that worked (comment disappeared).
It appears that if you comment while track changes is on, comments after a document is saved-closed-reopened are somehow seen by ‘track changes’ as part of the document text that is tracked/protected which causes an error in deleting a comment. This error is also limited to deleting, comment text can still be edited.
*I verified that the bug only occurs when a saved document is opened later. Comments made during the current editing session can be deleted (even if you save the document - the key is if you save and close, then the next time you open, the prior comments cannot be deleted until you turn off track changes). I also tried some suggestions here but they didn’t fix it: Read only content cannot be changed, no modifications will be accepted
Let me know if this was an intended feature, there’s a setting I need to change or if this is a bug. Thanks!
