Problem with menu by user role

Hello,
we are using “Nav Menu Roles” plugin to assign different menu based on user roles.
The problem occurs when we have active your plugin for all users (and register ones).
It seems that if we open one page with user role, for example ‘guest’, the menu is , let’s say menuA. Now if we login and open the same page as user ‘user1’ the menu doesn’t change to menuB but remains menuA

Regards,
George
