Problems with Facebook RSVP for Events +

I have everything setup for the social logins. I am running Twitter, Facebook, Google and WordPress for social RSVP's. I can login with Facebook, but it just shows the buttons. When I RSVP with the other social buttons everything works just fine. I tried checking and unchecking the already using Facebook scripts checkbox. Any ideas on why Facebook won't work in this instance. You can try it at http://levanchiro.com/events/2013/05/benefits-of-chiropractic-two-guest-patient-testimonials/

Thanks.
