Some of the thread prefixes appear to have the same color background as the prefixes box itself. That might be intentional, but when they're actually used for threads these prefix tags appear just as a different font to the left of the actual thread title rather than as a tag, making it look like the thread title got kind of broken. I made
picture with handy red boxes to point out what I'm talking about, in case that description was lacking. Here's all the tags like this I found after looking at all the subforums:
Worldbuilding Exercises: Conflict Exercise
Group Jump-In Roleplay: Paranormal
Group Fantasy Signups & Plot Discussions: Gaslamp Fantasy and Historical Fantasy
Group Modern Fantasy Signups & Plot Discussions: Paranormal
Group Historical Signups & Plot Discussions: 1930s
Group Dice Signups & Plot Discussions: Roll20
Group Libertine Signups & Plot Discussions: Paranormal
Oh, and while I'm at it, the text for the prefixes box that says "Click for specific categories:" is black on dark grey in the Dark theme, and it's kind of hard to read. This is an issue for all the sections that have prefixes, not just the ones listed above.
