Hello,
We have several Groups that were created that were not 'out of box' groups (Under products > Jira Service Management) these groups we have created are synced and managed from an external directory.
When I try and make one of these external groups a default I get an error message -

Even after a few mins or days it is still the same.
Does this have something to do with these groups been created externally?
Like wise the out of box 'stakeholders' group has no members assigned, but I am unable to remove this as default as well.
I have admin permissions to Jira as well.
Any advice on this one? Or is it because these groups and managed externally, we cannot make them a default?
