When we're on the grading page for an assignment, we can easily sort the list of students by first name, surname, last modification date ... clicking on the column header. We can too filter by "Submitted", "Requires grading"...

The problem comes when I press the button for individually grade for one of the students. In the window that opens, always appear in the same order (by surname) and all users of the course (not filtered).

Finally, sometimes, there is a problem too when we click on filter button in individual grader, it seems blocked.

I have attached a small video in which this problems are visible.
