I posted this question 5 months ago, to no avail. The apparent impossibility of listing a submission only once for group subsmission is a major irritant to my colleagues and me and I would really appreciate getting some feedback on this issue,
In the 2.9 version of the assignment module, it was possible to list only one submission per group (for group submissions), by using the selecting the "submitted" filter. This does not seem possible in the 3.3 version. Even with "submitted" filter, all the students are listed, with each submisions repeated as many times as there are students in the group. Same problem with the grading interface (the "needs grading" filter does not act retroactively, so one ends up scrolling through numerous already graded submissions to find th eones that are not) Am I missing something? Thanks! Best, Eric
