Use case

We use questionnaire by group and/or grouping in our sites. And we want to know which people in the groups have not completed the questionnaire.

Steps to reproduce bug

1. Go to course with students/questionnaires
2. Create groups Participants > Groups > Auto-create groups
3. Create groups with 5 people each group, this will create two groups with 5 students
4. Go to questionnaire and edit settings
5. Go to Restrict access and add a restriction that students must match a group you created in step 3. Save changes
6. Go to questionnaire and click on Non-respondents tab
7. See that everyone in the course is displayed. When I expect to only see those in the group/grouping I restricted access to.
