Sorry for the delayed response. It does not seem to have worked.
The problem is similar to the one mentioned here:
The URL slug remains “trust_level_1”
For me, this issue is limited to trust level 1 and 2, the others seem fine. I tried resetting the name back to “trust_level_1” and back to Trainer with no success. Running Jobs::EnsureDbConsistency
does seem to trigger the update on the actual group name but it does not change the slug name for me or the name in the dropdown.
