Grades not showing up

Community Member
I've created a load of H5P assessments in a Canvas site and added them to Assignments as an External Tool. Everything seemed to be working fine and the grades were appearing when viewed in the Grades link. However now when I go to the Grades link the latest results are not showing even though I know people are submitting assignments.
It happened at similar time to when I added the Badges to automatically award when learners met criteria. Not sure if this is related. I've selected the Badges to now be awarded Manually and deleted the Requirements in Modules, but the Grades are still not appearing.
