Glad to hear that got you going. Again, this seems like a Joomla 3.3.x issue and not specific to JFBConnect. The same issue will likely happen if you use that setting in the mod_login form. We have it on our to-do list to investigate further, but the options you've chosen should get you going and accomplish what you need.
If you run into anything else, or have any questions, please let me know.
Finally, if you haven't already, please consider leaving a rating and review for JFBConnect, or our support, on the Joomla Extension Directory. It certainly isn't required, but is very appreciated:

Thanks,
