PopUp Pro showing unwanted content from Elegant Themes plugins

I'm having an issue with PopUp Pro showing content from the Elegant Themes' plugins Monarch & Bloom inside the PopUp content. The weird thing is that this issue only shows up on blog posts, not on pages.

You can see what I mean by clicking on the blue "Get a Quote" button at the top of the right sidebar on this page: http://csocially.com/about/

And then click on this post & you'll see the unwanted content: http://csocially.com/whats-new-wordpress-4-0/
