Hi Kathy Bielas !
Thanks for reaching out with this question.
The student has either dropped or been dropped from the expired class. When a student is dropped, they are removed from the class roster and any submissions they made to assignments in the class are no longer viewable by the student or the instructor of that class.
If instructors wish to view any submissions made by a dropped student, the instructor can simply add the student to the class again with the same email address that the student was formerly enrolled with. Once this is done, the student will reappear in the class roster along with any submissions that were made.
Please note: the class will need to be made active again before the instructor can add the student back to the class.
I hope this helps-- if you have any additional questions, I recommend you reach out to our support team directly at email@example.com. Have a great New Year!
