When you do the fill in the blank questions in a kanji schedule, and a kanji has 2 on/kunyomis, and you only type one, it gives you a message: "it looks like you haven't submitted every reading yet (one more kunyomi)", and you click enter once again, it still is correct as long as the reading you already had submitted was correct, even though you just didn't type the other reading
That's how it has always worked. That's not a bug i.e. it intentionally works that way (a kanji could have many more readings than just 2, so forcing you to include all of them could be brutal).
