Lists compile into plain text for epub and PDF

I’m having trouble getting a bulleted list to work when compiling to an epub. The list comes out as plain text (looks like Courier font), with bullets as asterisks. This is one document in my project, meant to be an appendix to my novel. Other parts of the document format correctly in a normal font, and I’ve experimented with other styles like Caption, and they come through compile as expected. It’s just the list that’s not working.
It also didn’t work for me in PDF.
I’ve tried creating styles for the two levels of lists, and adding those styles to the compile format, but that didn’t help.
Any suggestions?
