Hey Lisam,
first of all, thank you for the purchase!
The left-side boxes are the so-called icon menu, and they use images instead of Font Awesome icons; you can set up the menu in the «Icon Menu» tab of the Theme Options panel, where you can create the items, upload images, set up links, etc. Should you have other questions about the menu or any other part of the theme, do not hesitate to contact me!
Sincerely,
Andrii / Satori Studio
