Facts widgets not showing third icon

This is my site
http://dummyblogger.com/test/
Here I add the facts section at last. You can see the third icon is not displaying. I changed it several time. Please suggest the solution.

Thank you.

Hi,

I’ve checked your site and seems like you not update the theme to the latest version. The icon is from font-awesome and “Pocket” icon is available in version 4.4+ (your current font-awesome version is 4.3)

I suggest you to update your theme to the latest version of Sydney.
