There is a Application menu called Routing Rules can be accessible for rr_admin role members, one of the user having rr_admin role but he is able to see the Routing Rules Application menu in Navigational bar.
Please make sure 'Name' field in Application Menu is not be empty. It's not mandatory field but if this is empty, application menu won't be visible in app navigator to users even if they have required role, unless user has admin role too!
