Easy Profile - Joomla Extension

Profile Menu Item doesn't work as expected. We have implemented Easy Profile in a page with different main menus for different departments and a different site style for each. Each main menu contains a link to a profile list, which is filtered by sql statement to ouput the users filtered by department. By clicking on the menu item the list is displayed with the assigned style. This works fine...

But we if you click on a user name to view the single profile the style isn't assigned anymore. We have created a hidden menu for each department with an item "profile" and assigned this menu the appropriate style. In the department menu we set "Profile Menu Item" to the equivalent hidden menu item. E.g.:

Hidden Menu 1 > Profile (alias: menu1-profil)
Hidden Menu 2 > Profile (alias: menu2-profil)
Hidden Menu 3 > Profile (alias: menu3-profil)

Menu 1 : Profile Menu Item > menu1-profil
Menu 2 : Profile Menu Item > menu2-profil
Menu 3 : Profile Menu Item > menu3-profil

If we set "Profile Menu Item" to "default", the style addressed to the home item is loaded and the behaviour is correct.
The link looks like this: https://www.xxx.com/menu1-profil/john+doe.html?back=1

If we set "Profile Menu Item" to "menu1-profil", the default fallback style is loaded and the behaviour is not correct.
The link looks like this: https://www.xxx.com/component/jsn/john+doe.html?Itemid=&;back=1

All other modules, that are assigned to be displayed with the menu profile link, will be not displayed, too.

For testing purposes we have published "Hidden Menu 1" on "Department 1" page, but the same behaviour appears. The style is not addressed correctly and the assigned modules are not loading.

If we do this with the core search function all works like expected. Any suggestions?
