When I load your page, I can see the GA code in there so it's THERE and that's all Google should need... Is UA-2109736-2 your right GA 'code'?
Are you using any GA filters on their site?
The only odd thing I see in your source code is, at the bottom, there's this:
<!-- include google analytics -->
and then a huge section of code I don't recognize (nor see on my site, and I too am using Yoast). Maybe you have a function or something else that's calling in the code twice?
