Problems with Peer Work when self-evaluation is turned off

Hi Peer Work devs / contributors

Are there any known problems with Peer Work when self-evaluation is turned off? My contribution and calculated grades are way off when 'self-grade' is set to No.

Even if all students give each other identical marks (which should in theory result in them having an equal contribution and calculated grade), the results don't reflect this. In the below example, 4 students in total each mark their 3 colleagues, but not themselves. All students marked all other students '3' on every scale / criteria. The same problem also happens if the scoring is done randomly.

Name Contribution Calculated grade Penalty Final weighted grade Revised grade
Test Student 1 0.0000 0.00 0% 30.00
Test Student 2 0.4444 26.67 0% 43.33
Test Student 3 1.1111 66.67 0% 63.33
Test Student 4 2.4444 100.00 0% 100.00
Total 193.33 236.67

When the same test is run with self-grading turned on, and with all students awarding '3' on every scale / criteria for all other students, including themselves, the problem does not occur.
