Comments Evolved plugin issue

Hi,

I am using comments evolved plugin for my blog, but whenever I am posting about a post on google+, even that sharing is also getting added as a comment. I have shared the a post URL in 6 G+ communities, then all those shares are added as comments.

Can anybody help me how to disable this?

Thanks,
Praveen.
