[Plugin: Google Comments] WordPress doesn't count G comments

Hello,

I’ve installed a plugin that allow commenting entries using Google+. Everything works fine, but I’ve one problem. WordPress doesn’t count these comments. The number of comments should be displayed on the main page of my blog but it doesn’t. Is there any solution to force WP to count them? Maybe change something in PHP code, or maybe G+ doesn’t allow to count them?

Sorry for my English, it isn’t perfect. 🙂
