In a docx document imported from MS Office, different parts of the text have different line spacings.
Resetting the line spacing with Paragraph > Indents & Spacing > Line Spacing does not help.
Format > Clear direct formatting does not help.
Deleting linebreaks does not help - new linebreaks are still set with the old spacing of that particular part of the document.
Copying and pasting linebreaks from another part of the document does override the hidden settings - but is a cumbersome workaround.
What hidden settings are there, and how to get rid of them?
