My school is using Moodle2.4.
My students had to give a presentation and I used an assessment form to grade their work. For some reason, I can no longer select/ unselect the items of the assessment form of the works I have already graded once ( one of the criteria is the way the behave during their classmates' presentations so I need to be able to modify this section if their behaviour changes - I can still modify the others' grids). I can't change the final grade either except in the gradebook. In the gradebook the marks appear in brown as bypassed. If I untick the bypassed element, save the changes, it comes back again the next time I go to the gradebook.
Do you have any idea how I could have locked the grades?
