How to get sociable icons to look like the screenshot

How do I get the sociable links to actually show up like the screenshot on the main plugin page.

I want the bottom row of twitter/fb/google+ but mine does not look like that. The buttons are all different sizes and the background of the number area is not grey.
You can see it here on my page.
