If there are many students with the same last name in a course sorting can be difficult. As a teacher, I would expect the first name to be sorted automatically in alphabetic order when I sort the last name.

The problem: In courses with many students (700 or more) there are always some students with the same last name. When grading, for example in an assignment, a consistent alphabetic order is very important to avoid mistakes.

Steps to reproduce:

• Add a new course
• Add at least four students with the same last name but different first names.
• Sort the students by their last name.

Expected result (as a teacher): The students are sorted alphabetically. The first name follows the correct order (from A to Z or Z to A)

Actual result: Only the last name is sorted alphabetically. The first name is not sorted. (see Screenshot 1)

Actual workaround: First click on the filter “First name” and then on the filter “Last name”. (see Screenshot 2) With this workaround the first name and the last name are correctly sorted.

Suggested solution: The filter for the last name should also apply to the first name.
