Granted, the warning says clearly “If you deselect Undetermined, you will not see most content”, which places the onus on the individual user, as apposed to logic built into Lemmy on which posts/comments can be viewed, while also leaving it to each user to have to weed out alternate languages for their views which are incorrectly set. This is indeed leading to many posts simply not appearing (as designed and intended), which is less than ideal when trying to grow a user base/community.
If you’re on desktop you can hold ctrl and make multiple language selections. I have undetermined and English selected.
As to why this is even a thing that needs to be set I have no idea either.
I couldn’t figure out how to make selections at all.
I still don’t know how to do this or understand exactly what this feature does
I feel like it should filter out posts that are not your language. So in theory you could have multiple languages in a single community and each user will only see their own languages selected
