Thank you for reaching out to us about this. It looks like the contacts that had used the Facebook Sign-Up Form were already in your active contacts prior to signing up. If this happens, the Facebook form will show that a sign-up occured, but they will not show as new contacts. Because our system does not allow for duplicates, the contacts would just get updated and have any new list added under their profile that might apply to that form. I hope this helps.
