The grade shown in the mod/assign grading table seems to be inconsistent when multiple attempts are done in a "Students submit in groups" assignment.

To reproduce:

• Create a group
• Add two students to a group (group A)
• Create an assignment with this configuration:
  • "Attempts reopened": Manually
  • "Students submit in groups": Yes
• As a student in group A submit a task
• As a teacher go to "View all submissions"
• As a teacher click on grade button for the student
• As a teacher grade the student with 11 (for instance)
• As a teacher go again to quick grading table
• The grade column shows 11 for all group members
• As a teacher "Allow another attempt"
• As the same students in group A submit again
• As a teacher go again to quick grading table
• As a teacher click on grade button for the students
• As a teacher grade the student with 33 (for instance)
• As a teacher go to the grading table again

Look at the grade column. You should see somehing inconsistent:

• The grade for the student graded may be 33 or 11
• The grade for the other student may be 33 or 11

You can try opening other attempts and do the grade / reopen loop. You'll see that the grade column will be filled with random grades for other people.

What we should expect:

• When an attempt is reopened, no grade should be displayed to be consistent with the "students do not submit in groups" setting.
• When a student in a group is graded and the same grade is assigned to other members in the group, this grade should be displayed in the grade column for all the members
