This is happening in the new and old version of the gradebook in the individual student gradebooks. it is calculating a final grade, but it no longer shows the calculation for formative and summative. This was working fine before our winter break (Dec 20th).
All cases related to the New Gradebook should be sent through our regular escalation processes. We only recently asked that bugs not be reported in this space, so the support agent may have just forgotten. Feel free to reply to that ticket and ask that it be reviewed for our engineering team.
