NSTextView (macOS) set font in interface builder ... broken?

i just have a simple mac app, trying to set the font for an NSTextView in interface builder. IB UI says No Font, but when i try to select a font, it keeps saying No Font (e.g. that bit of the UI doesnt seem to work at all). xcode 13.4.1. any ideas?
