JFBConnect doesn't create your meta description title. My guess is that you're using an extension to automatically generate the meta description based on the contents of the page. If so, make sure that those plugins are ordered before JFBConnect's plugins. There are 2 plugin groups to check: Content and System.
Hope that helps, but if not, let us know what you're using to generate your description and what type of plugin it is.
Thanks,
Alex
