I ran into the same thing. I split my Lab category into Lab-Document and Lab-Questions, splitting the weight percentage. I changed the [[Code]] in classroom to reflect, and the Categories under the Settings Tab to all match [[LabDoc, 100]] and [[LabQs, 25]]. I did an Import and they matched in the colums LabDoc and 100 Weight, etc. However, the Grade column say "No Grade" for every student, yet each assignment has a score and percentage score for every student for every assignment. So the raw scores are there, the over all average is not being determined. I did not disturb any other columns so not sure what happened. I even made a Copy of the class and resetup a the Classroom and did an Import but it is the same. I shared the file with Tony and you all. Hoping to know what the fix is.
Thanks!
