Modification of permission scheme should not result in warning

I modified the permission scheme of my JIRA Service Desk so that Customers and Service Desk Agents CANNOT delete issues. Doing so results in a warning stating that the "service desk project may not work as expected".

This warning should not appear at all based on the minor permission scheme changes I made. My IT department does not believe that customers nor service desk agents should have permission to delete service desk issues. Only service desk administrators should have this privilege.

I ended up reverting back to the original permission scheme because I was receiving too many emails from my service desk agents informing me of the warning they're getting.

Please fix JIRA Service Desk so that a warning is NOT given when we make justifiable changes to the permission scheme.
