Eek indeed! I’ll get that changed right away!
Good question, I’ll put this through to our content team and let you know what they say, it might end up being a case of making がつ into a “grey shake” answer.
Update: We ended up adding a “grey-shake” prompt if you were to type がつ for 合 now.
for ones like this always mention @Mods so they can see whether it should be added to the block list 
Thanks, added!
For any that give a coherent result, it’s probably a good idea to ping @Mods.
Just a little testing, but perhaps it matters @Mods – 【LV1-5】Do you know how to answer 何人ですか？

Hey polv! I just checked and なにじん is also marked incorrect. Thanks for bringing this up to our attention. I’ll go ahead and make a ticket for this to see if we want to add a warning for the reading and meaning.

In contrast, for 暑い, “hot weather” is an accepted answer.
hmm
edit:oops I didn’t mean to make this a reply
always a good idea to tag @Mods when something like this comes up so they can fix it
