AddThis

Google Analytics integration

Hi,
I am having difficulty getting Google Analytics to track each of the social sharing actions. I have tested the following share actions on this page: http://www.pinpointppc.net/cheese-blog/lemon-cheese/
* FB Like
* Tweet
* G+
* Pin It
* Email

All the actions show up in AddThis Analytics, but only FB Like, G+, Pin It, and Email show up in my Google Analytics report, not Twitter. Could you please look at my code on http://www.pinpointppc.net/cheese-blog/lemon-cheese/ and let me know if I have done something wrong? Or is this a known issue with the Google Analytics integration beta?

Thanks!
