Huhu, that language option always causing huge issue, i've learned changing that option will cause me unable to post and some people reported unable to see a lot of comment. It's annoying.
Undetermined is the default, and i think Cafe set to undetermined as well, so if you pick English you can't post it to community that isn't set to English. It's very janky. And if you change your language setting in your profile setting, you won't be able to view a lot of comment and post as well.
Honestly, i still have no idea how that thing works, so better just leave it.
