Jetpack share buttons not working

The Jetpack share buttons on my page do not work… instead they open the blog they’re attached to in a new window. (see http://datingshakeup.com)

The buttons work if I change the ‘button style’ to ‘official buttons’ in Publicize Sharing Settings. But if I used ‘official buttons’ the Facebook Like button has no pop-up dialog to post anything to the users Facebook profile. Whereas I’ve noticed that the Facebook share button used on this page (http://jetpack.me/2012/11/08/jetpack-2-0-publicize-to-facebook-twitter-linkedin-tumblr-post-by-email-photon-infinite-scroll/) with the button style ‘icon + text’ opens up a ‘Share this link on your timeline etc.’ dialog, which I would like to have.

Jetpack is my only active plugin. All others are disabled.

Any help appreciated.
