Cloze test

In a recent text two lingqs never appeared in the cloze test. I have discovered that the associated phrase did not, in fact, contain the words in question. I changed the phrases manually and now they do appear. But how did the original problem occur?

Hi @bill232 - sorry about that! It is hard to say not seeing the phrase. Maybe a term in that phrase was in a different form? If you experience this issue again, please send us a screenshot. It would be very helpful!
