As a noob this is likely me, but I tried to start a community on another server and I can’t see the post (my other account used to make said community) made and set as english. Unless it’s just me being a noob, that can’t be good. A cursory look seems to confirm that I can’t see anything aside from “Undetermined”.
You should should choose both “undetermined” and all the the languages you want to see. From what I understand, “undetermined” makes it display posts for which the poster didn’t specify a language.
