If any activity is hidden from within the gradebook, the course total will not appear in the overview report for the student.

Admins can see the course totals correctly in the Overview report. When logged in as a student, the overview report only displays grades for courses which contain no hidden activities. Courses which contain hidden activities have a - dash where the course total should be.

The dash was replicated on Moodlerooms servers as well as on the 1.9.7 Moodle4Mac install. On demo.moodle.org, a 0 appeared instead of a dash.

When the student goes to their user report, their course total displays as it should.

To replicate:
1. Assign a few grades to a student.
2. Hide one of the activities from within the gradebook.
3. Login as the student and view the overview report.
