I have set up a Canvas quiz (actually a final exam) that is drawing 60 randomized questions from a bank of over 100 questions. I have had several students report that they are getting one question repeated sometimes 10 or 15 times. I have checked their exam attempt and I do see one question repeated over and over, with other questions mixed in. What is going on and how do I stop that? If I delete that question will the same thing happen with another question?
