Have I Been Hacked?

I am in the process of trying to get politicallygrounded.com set up and on a few blogs have noticed a strange Adsense id ca-pub-3374715123484136 This is not my adsense id and it seems it appears at the top of all the blogs, a blog that I created has it as well at weekly.politicallygrounded.com the top pub is the one above and the adsense ad below the post is mine.

The thing about it is, I have supporter installed, I have it set to show adsense above and below, the pub id in supporter settings is the same as mine in both instances, but my above is not showing, rather the pub id above is. I do not have any adsense plugins available to non supporter blogs and I do not have any plugins activated at weekly.politicallygrounded.com so either I have missed a setting someplace during set up or I have been hacked somehow, any help or suggestions would be greatly appreciated.

Thanks In Advance,
