Description
In the Original course experience, the Full Grade Center exhibits inconsistent and unreliable sorting behavior for assignment columns under a specific combination of conditions.
The issue occurs when:
At least one student enrolled in the course has not submitted the assignment, resulting in a mix of submitted and non-submitted attempts.
All submitted attempts are currently in a "Needs Grading" status, meaning no grades have been assigned yet.
The assignment’s Primary Display setting is configured to a non-numeric format, specifically Percentage, Text, or Letter.
When these conditions are met, attempting to sort the assignment column (either ascending or descending) does not produce the expected ordering. Instead of organizing students logically—such as grouping submitted attempts, unsubmitted attempts, or ordering by status—the sorting appears incorrect or inconsistent, making it difficult for instructors to efficiently review and manage submissions.
This behavior suggests that the Grade Center sorting logic may not correctly handle a mix of "Needs Grading" statuses and empty (non-submitted) values when the display format is non-numeric. As a result, instructors may experience confusion or delays when trying to prioritize grading tasks or identify which students have submitted work.
Steps to Replicate
Log into Blackboard Learn as an instructor
Open course Original Course (regular course created previously)
Enroll student and student2 in the course(regular students created previously)
Go to Content > Assessments > Assignment
Create a new assignment titled "Assignment Week 1"
Set Points Possible, set the Primary Display to Score, and click Submit
Enter Student Preview without submitting an attempt
Exit Student Preview
Log in as student and student2, and submit an attempt for the assignment
As the instructor, go to the Full Grade Center
Click the "Assignment Week 1" column header to sort submissions
Observe that sorting works as expected
Open the column menu (chevron) for "Assignment Week 1" and select Edit Column Information
Change the Primary Display to Percentage, Text, or Letter and click Submit
Click on the "Assignment Week 1" column header again to sort submissions
Observed Behavior:
Sorting by "Assignment Week 1" breaks.
Expected Behavior:
Sorting by "Assignment Week 1" still works as expected.
