When I attempt to modify a multilevel list, by promoting or demoting sections, the numbering formatting goes away for the section and any subsections underneath it. I have to go up and click on numbering again for each section and subsection.
There is actually a multiline list style that does this. The iconography doesn't quite make sense but I'll just post a pictureof the options in question. The one that is X'd out looks like it will give you numbering, until you change the text to be a heading, then the numbering goes away. Once I saw that, I looked closer at the styles and saw the one with the checkmark, which does what I want.
