Group member lists not sorting on group set editing page

Problem:  When editing a group set, the list of students will not sort by last name (or other criteria) as expected.

Solution:  This is a defect, but Blackboard has not indicated a future release in which it may be fixed.  In the meantime, a workaround is to open the Grade Center in a separate tab or window, select the students in the Group Set using a smart view, and sort them as needed. In the other browser window, the group set can be managed normally.
