Floating Social Sharing The Wrong Page

Hello all and hope you are having a happy holiday. I have a small issue on one of my sites concerning the floating social plugin. On internal pages it is working flawlessly, however on the home page there is a problem.

When a user chooses to share the page on Twitter it is pulling the most recent post address to share not the home page address. Is there a way to correct this?

It seems that the other social networks are sharing the address of the homepage, just not twitter.

Thanks in advance for any suggestions,

Nick
