Services Section

I’m working on setting up my site using the Medihealth theme and like the way the Services section works, however, it is not calling any featured images or thumbnails in this section. Looking at the code, it appears that it calls on the medihealth_icon metadata tied to the page instead of the featured image. I have tried using the various versions of the font awesome it calls for, but it only ever calls a square box. I tried installing the font awesome plugin to no avail.

I would prefer this section to call the featured image for the page but I can’t figure out how to do this.
