I was trying to add Japanese 単語帳 into a list (using English), but there was an error saying that the word is not in the dictionary. I tried adding it to the dictionary and there was an error saying that it is already in the database while showing translation in Italian...

How can i add it in English?

Looks like we have marked this word as a mistake for some reason--I'll ask Jeremy to check it out. Then on top of that, it must be buggy to say that it doesn't exist and then say that it already exists. Thanks for the heads up; perhaps we can improve this.

I don't know why it was marked as a mistake, but the English definition was missing as well.
It's fixed and will work for both English and Italian now!
