Jira Software does not seem to remove no longer available entities from the project permission schemes after uninstalling modules, in this case Service Desk. The existing permission scheme which is set up on projects (which have now been moved to be business projects) still work, but editing the permission scheme bombs with a 500 error on the server; the client screen simply stays blank.
How can I properly remove the remaining permission entities/elements which are now defunct (due to the service desk uninstallation)?
