Yeah, Facebook can take a little time to update a few things as well as any caching you may have enabled on your site can delay updates. Hopefully it's all going well now, but if you run into anything else, just let us know!
Finally, please consider leaving a rating and review for JFBConnect, or our support, on the Joomla Extension Directory. It's not required, but certainly appreciated:

Thanks, and good luck,
