Hi @41844108
OneNote is not a word processor, so the numbers in the Paragraph Spacing dialog box work slightly differently than numbers in Microsoft Word and other Office programs.
In the Paragraph Spacing dialog box, the numbers in the Before and After boxes can cause confusing results, depending on how the text is formatted.
Unlike Word, OneNote doesn't show hidden paragraph marks. If you use soft line breaks (Shift+Enter) in your notes, OneNote treats the text as part of the same paragraph and applies spacing only before or after the entire block of text (paragraph) (before or after hard paragraph return (Enter).
