Hello David,

I've had a similar problem. I've no idea why it happened, but grades entered were not appearing in the gradebook, just a dash, as you said. I was not using a meta-course so I didn't have that problem.

I tried a variety of things, and found that if I re-entered the grades in the activity (not in the gradebook directly), and then saved them of course, the grades appeared. In one activity I printed the results so I had a record, then deleted the entire activity, made a new activity, and reentered the grades. They appeared fine after that.

A work-around solution is to go into the Gradebook, turn editing on, and manually enter the grades. This 'override' function replaces whatever they received in the activity. Once you've done this, you can reverse it by clicking the 'edit grade' icon next to the grade in the Gradebook, and then un-check 'overridden'. The grade then reverts to the grade from the activity. You might want to try this (enter a phony grade through the override function, save it, then cancel the override) and see if the original activity grade pops up. I have a feeling this will work. Of course, this is all time consuming, but if it is only a few grades, it would work.

This happened to me with only one course (2.4 version) but it happened with a number of activities in that course. No idea why.

If these ideas don't work, let me know, and I'll play around a bit with it later today.
