I'm having some problems which I can't really explain.
I set up some quizzes weeks ago, including 3 types of Overall feedback, with grade boundaries at 100%, 70% and 40%. When I go into quiz settings to make any changes, it has somehow forgotten that I had put 70% and 40% into the Grade boundary boxes. Therefore, when I try to save, I get a message saying I can't leave any gaps (see GradeBoundaryProblem1.PNG). This is strange, as I know I definitely filled in these boxes months ago. Anyway, I can just fill them in and save - problem solved (for now at least - but I am wondering whether the figures might disappear again soon!).
But the real problem is that for 2 of my quizzes, the writing in the Feedback sections has completely disappeared, and the Grade boundary box is uneditable. I cannot click into it to add any figures. I am attaching GradeBoundaryProblem2.PNG, but you can't really see the problem from the screenshot. You can see that the Feedback fields are empty, but what you can't see is that it is impossible for me to edit the Grade boundary. It as if this box has been disabled.
Many many thanks in advance,
