When you created your list, you specified the Font attributes of the numbers rather than leaving that undefined. If the Font attributes were undefined, the numbers would have the same font attributes as the paragraph style. This would allow "Level 1" and "Level 1 Heading" to have default number formats which align with the font settings for those styles.

Unfortunately, removing all imposed font attributes from list numbers once put in is not possible via the GUI interface (in my experience). You can wipe the type name but not the size. It might be possible to do it by editing the XML settings in the document but that would be kind of obscure.

Since you don't want to use macros to set things up I think your only fix is to recreate the list from scratch and make sure NOT to apply any Font settings to the list items this time.
