The archive list doesn't display in nested/offset list style. Instead, whenever years or months are expanded, every list item appears flush left with the parent item above it. Here's a screenshot of how the list looks with one month expanded:

I've tried everything I can think of to alter the CSS, and nothing seems to work -- altering the CSS in the "Settings" menu, following instructions on how to add the CSS to my theme's styles and altering it there, even (as part of troubleshooting desperation) adding CSS styles to the ul and li tags generated by the PHP file that creates the list. Still, I get nothing but the same flush-left list.
I've done a fresh plugin install, to be sure that I'd eliminated all traces of my mucking around. Anybody have any ideas on how I might style this successfully?
