Hi CaptainStarbuck.
Paragraphs in Scrivener can only have one style assigned to them.
And since a list is a set of short paragraphs, they can all have their own style.
My point being:
You don’t have to undo anything nor convert to default formatting. Just create paragraph styles with the desired indent and then apply that to your list(s) where and as needed. It’ll overwrite any paragraph formatting from before and, from what I could read on the forum, should tame them in their erratic behavior.
Here is a bunch of styles you can use for your list, that I had designed for another user.
Should you wish to use them, just download this tiny project, then import the styles from it into your own project.

The number after each is the actual indent in inches. So from 0.25" to 2.25".
