Basically, each of the buttons inside your Flare bar are set up by those services (such as Facebook, Twitter, etc.) to only be related to the page upon which they're displayed. This is a security measure that each of those services employs to ensure that when you hit the "Like" button, you are in fact Liking/Tweeting/sharing that specific page, and not something else. It's built-in protection against a practice known as "Likejacking".
This is something we're working to address. In the meantime, you can prevent Flare from showing up on your blog index page, by adjusting your Filters to exclude those index pages. Learn more about Filters here:
