State related to session saved last becomes the current one for all others saved sessions as well. 

1. Log in to the default session. In tool Session and Startup  -> General tab, select Display chooser on login then log out and save session. 
When option Save session for future login is used for the first time it creates a session named by default Default, despite current system language is Finnish which is just smother issue related to translation.

2. Log in and select New session as second session . Do one change (may be the appearance style). Log out and save session.

3. Log in to the default session. It is noticeable that he second session has replaced the one of the Default session. Let's bring back the style to its original state then log out and save session.

4. Log in to second session  It is noticeable that Default session has replaced the one of the second session.

5. Back in Default session, in tool Session and Startup  -> Sessions tab, select Clear saved sessions. Log out and save session.  At next login. an entry session named with the already used second session's name is still displayed in sessions list despite the previous clear task, while name should be «Default» .

As enhancement request related to that issue, would be to inform at the logout and saving session, along with the user's name, the current session’s name as well, so that changes made during a session were indeed the ones that were meant to be made in that session.
