Role Change on edit profile is not working

In this page, we have some functions to edit other user profile and change his role from frontend.

In the profile form is used a profile radio button. It shows 4 um_roles (um_prestador, um_event_organizer, um_suscriptor and um_contenmanager).

All admin users, can change the subscriber role with “edit profile” from member user page, but from 2.6.3 version, it is not working anymore.

The admin user can go to member page, can select a user (i.e. um_suscriptor) and select the new user role to assign it (i.e. um_prestador) but the user still shows with um_suscriptor).

The page I need help with: [log in to see the link]
