1. When adding style separators, always work with nonprinting marks displayed (you can click the ¶ button on the Home tab).
2. When editing the numbered list, always place the insertion point inside the first level 1 item of your list. For heading numbering, this means the first Heading 1 paragraph of the document. Does MacWord have the ribbon? In that case, you should then display the multilevel list dialog box via Home tab | Multilevel List | Define New Multilevel List. The command is misleading, but it works as long as you have clicked in the correct paragraph as mentioned above.
3. Try resetting formatting in the affected paragraph. In WinWord you would do that by selecting the paragraph and pressing Ctrl+Q.
4. How did you adjust the headings, specifically?

6. I think you are describing content controls.
