I am a teacher of English in Catalonia. I've started to use the Questionnaire tool. Everything was Ok until sth strange happened. The student gives the right answer but it's marked as wrong.
Can anyone help me? Can you see any difference? It doesn't happen in all questions

You can't see the answer but it's exactly the same as the right one
