Has it been pointed out that NetworkManager takes all interfaces it 
controls down when you log out?
It then brings them/it up again when you log in.

In other words, NetworkManager is user oriented.  This allows the user 
to control network services customized by user.

The messages you show there are 'normal' if you simply logged out.

When my wife logs into my laptop, she does not get my work VPN 
connection as an option.  That is cool stuff.

Good Luck!
