I have a quiz (graded anonymous survey if that is important), which I am trying to duplicate 11 times. Strangely enough, there is no "duplicate item" function in canvas and I was following the suggestion from this forum. Basically, I copy this quiz from the same (current) course. Ok, the first time it worked fine and I have now 2 quizzes. I renamed one and tried this again, this time with two of them. Now, only one got copied.
