I have created 4 courses. When I go to participants and see the students enrolled in the course, on 2 of those courses, I have the following 2 problems:
1. The sorting link on the top of the list does not appear.
2. All the students show up in different boxes, with options like "Activity", "Login as", "unenroll" etc.
3. On the other 2 courses, the sorting link shows up and all the students show up in a single table.
One thing I would add is that on point 1 and 2 I have less than 20 students, and on point 3 I have more than 20 students. Is that the reason? If not can somebody please let me know how to show the sort link on the top of the students list.
