Having an issue with social icons in the footer

This is the website I’m working on Fenix.
I am using the Divi theme from elegant themes, but have created a child theme. Because this website is a real estate site, I am also using the optima express plugin that generates MLS listings, and searches for homes. So, some of the pages like “properties” and “contact” is an optima express page that was created when I signed up for the plugin. The divi theme has four social icons in the footer – FB, twitter, google+ and rss, I want to change the last two to pinterest and linkedin. I imported the footer from the parent theme and I downloaded the font-awesome and I put the two icons (pinterest and linkedin) in the list in the footer. The issue is that it seems to work just fine on the optima express pages but not on the other pages that I created like “about us” or “blog”, if anyone has any suggestions, that would be awesome. My client wants this site up like yesterday! When you inspect the element on the pages that the icons aren’t showing up on they are there in the code, they just aren’t displaying for some reason. Thanks, guys!!
