[minor] All answers are correct answer

I’ve just stumbled upon a case in unit 16 of Korean 2 course where all presented answers were the correct answer.

Is this a Desks provided course? I’ve seen this happening with new records added since the last two weeks or so.

No, that’s the official “Korean 2” course from Memrise.

I see this in the app (but only when learning on-line), and in the web version, too. And it’s always the correct answer that gets multiple entries, never one of the other ones, ie a bit of a give-away, even if not all entries are the same.
