When survey results displayed by question, only one question shown
I've given some students a survey where the first question was a yes/no. In Reporting, when I want to see the "Detailed report by question", only the first question is shown; although there are arrows for next/previous and they are not greyed out, they don't work (there's not even a hand-pointer on hover). So I can only see the results for this first question. The other reports work correctly.
I wonder if it might have anything at all to do with the fact that some students did not answer this first question (selected neither Yes nor No).
