Feedback not visible to students

I just upgraded to the new version and now my students are unable to see any feedback.

I checked almost all the options for feedback after the quiz. A screen shot is attached.

When I log in as an administrator, I see what I expect.

But when I log in as a student, my results are:

1. With MC questions, I see the columns but they're all empty. (screen shot attached)

2. With matching questions, I see the information I expect, except with the Correct column. That information is missing.

I have two screen shots attached from logging in and viewing results as a student.

Note: students are authenticated users and they do have permissions set so they should be able to see their quiz results.
