Emma,
thanks for the hints. I managed to fix the problem for now but I am not sure if the fix is going to cause some issues in the future. As you suggested under Users/Permissions I found that 'students' were added under permit for "Receive grader submission notifications" After reading the description for the notification online which reads as follows
- This capability allows a user to be notified of assignments submitted by students.
- This capability is allowed for the default roles of manager, teacher and non-editing teacher.
However I am not sure if this is going to cause any side issues when it comes to students receiving any notification from the grader when grading is done. If not in my humble opinion this permission is very confusingly named and does not really much the description.
Regards
Salim
