Groups not working in 3.8

[steveradford]

I have this block on teachers dashboard pages. We have courses with multiple teachers and students, where students are separated into groups and teachers are only a member of one group, however the block is still shows each teacher all assignments that need grading for all students in all groups, not just their own. All assignments have been set-up with Group mode = Separate groups. Grouping in all core areas of the site (e.g. on the grading pages) works correctly.

The info on the Moodle plugin page states that the block is configured to work with groups (that is, teachers will only see the assignments submitted by students if they are both members of the same group) but that doesn't appear to be working.

I'm on Moodle V3.8 running the latest version of the block: 3.8.0.0

I also have on my teachers pages and need to separate by group.

This is not working in 3.11 either. This makes it impossible to use in any site where courses use instructor based groups.

We have just installed the Grade Me block and it works well except that the grouping is not working and teachers are complaining that they are seeing assignments from all students instead of just those in their group. Is there a fix for this or something I can try?
