After installing the "Protected Content" plugin, the user name changed visibility. Independent of the display form chosen during user registration, automatically the default display becomes the username (even if I have determined that the form of publicly present that member is Name + Surname or Surname + Name). I really need that defined in the user registry is the default and not the user name.
Note: Once the user is created, the chosen pattern remains visible for some time. But when a new log, which was previously set will change to display the user name, including the administration bar, where the default is now "Howdy, [username]".
