The "Connect this account" will show if the user hasn't connected with all networks. In your case, it sounds like you may have authenticated with Facebook, but there is no Google profile connected to your account... which is why that button is showing, but not Facebook's.
The previous bug was that the "Connect this account" text would *always* show, even if the user had connected with all available social networks.
If you don't want the option to connect more social networks to show, you should disable the "Show Connect Account Buttons" in the "Logout View Options" of the SCLogin module.
I hope that helps answer your question, but if you're still having issues, please let me know.
Thanks,
Alex
