We are running Moodle 2.7+ (Build: 20140529). When a specific 'Lead instructor' tries to enter into an assignment from the course page, and then clicks on the option "View/Grade all submissions", a text appears saying there is "nothing to display".
When I do the same using my 'Support' role, I see the full list of submissions to be graded (see images that follow).
Even when I use the "Switch role to.."-option to change my role to 'Lead Instructor', I can still see the table that our specific instructor is not able to see.
Any ideas of why this could be happening
