Can't delete MySQL user after "cPanel Account Restore"

I recently switched from cPanel to CWP. After I backed up my cPanel account and imported it into CWP, everything functioned, but a weird thing happened.

CWP created MySQL users from the cPanel backup that can't be deleted. When I try, I get "Error
Invalid System User". Is there a way to resolve this?

The MySQL manager functions can be buggy. Try logging into phpMyAdmin and look at the DB there. You should have full control as the root user to make any adjustments or deletions you need.
