Attributed Label and Dark Mode Not Working - sometimes

I’m working on an app with a screen containing a bunch of labels, some attributed (so I can get bold or underline) and some not. One of the attributed labels is not switching to a light color when I use dark mode (see image). I could create an IBOutlet for the problem label and manually switch the color when in dark mode but that’s kind of a hassle, and shouldn’t really be required. I tried copying one of the ‘working’ attributed labels to this spot but the problem persisted. Any thoughts on what could be going on? If it matters, the attributed labels are all set up in interface builder. The font is ‘System Font (Default)’ in both the ‘working’ and ‘not working’ labels. Thanks.
