At some point in time we lost the ability to preview rubric results for individual students. In the Grader Report, the Preview icon (magnifying glass) still appears next to quiz results but has disappeared from rubric results. I'm logged in as the Administrator, so I assume it's not a lack of permission. I've searched moodle.org and examined the Rubric Settings, but cannot find any way to fix the problem.
Please help me enable instructors to access Rubric results.
