Multisite Content Copier not connecting to Facebooks

Hi,
I'm having some issues with the Multisite Content Copier. When I create a post in our site cremafriends.com and select it go to the site group the post goes onto each site and also to it's respective Facebook address - great. But if I create a post in one of the other sites (ie. cremafriends.com/mainbeach) the post goes onto each site but not onto the respective Facebooks (ie. facebook.com/mainbeach). All sites have "Publicize" with Jetpack and are connected ok.
Are you able to help here?

Many thanks,
Claire
