Hi @caroline_hellst
I think the teacher used the 'assign to' function and at first assigned the assignment to a complete section.
The teacher should add a second 'assign to' box with the name of the specific student instead of replacing the section. Because from what you describe, I think they replaced the complete section for one student.
The solution is simple: in the assignment, create another 'assign to' box and reassign the assignment to the section that was deleted.
Save, and the results should show up again.
Let me know if this is clear, otherwise I can try again (and type 'assign' and 'assignment' some more 😁)
