I'm having a few issues with the Ajax Marking Block when used with groups.
I have a course with about 10 groups, each with a different teacher. If I log in as a teacher and set up the marking block it looks fine. If I then login as another teacher in the same course and set their block up, this second teacher students appear on the first teachers list.
I've been getting messages from various teachers that their marking blocks won't stay set up for them.
Courses are set to forced separate groups; Moodle 2.4.4+, latest version of the marking block.
