Icons in premade template not showing up in guttenberg or elementor

Hi folks,

Ok so, i'm testing the generate slideout theme and whether in Gutenberg or in Elementor i cannot get the social icons in the side-menu to show up correctly, i read that it was a conflict between icon versions but i have no idea how to fix the issue.

What is it that i should be replacing ?

Could you lend me a hand in resolving this issue please.

Thanks
