I confirm this information.
Additional options for role does not applied to the user with ‘ure_edit_roles’ capability, as such user can change any option for any role.
I will hide additional options for ‘administrator’ role in order theme not confuse users.
Thank you for notification about this user interface inconsistency in URE.
Working on the update I changed my decision – it will be more correct to apply additional options for any role, including administrator. It will give ability for customization for any users, including admins.
This update will be available at the 1st decade of July, 2018.
