Moodle 2.6.
A Teacher has used "Students submit in groups" and "grouping for student groups" in her assignment, but appears to have omitted certain Students from Groups and Groups from the selected Grouping. On discovering this, I believe she added the students to Groups and Groups to the Grouping, but this was after submissions had already been made. (I can see no reason for her to be using Groupings at all).
There is now a default group submission, visible as all non-group members' submission (including Teachers, Admin and students who are not in Groups and have made no submissions) - and I can see no way to remove it. The student who submitted this assignment has been moved to a Group and no submission is reflected for her.
Students who were members of a Group in the Grouping when they submitted can view their submissions.
For others, clicking on the assignment gets error/moodle/nopermissiontocomment link on a page with no theme.
Is there anyway to remove the default Group submission? Why can't Students access the assignment? Why are they being redirected to comments?
In the interim I have made another assignment for students who cannot access the assignment due to error/moodle/nopermissiontocomment and asked the Teacher not to use Groupings in future assignments... I can't think what else to do.
Any pointers would be greatly appreciated
