Broken to the top icon but social media icons are showing

Hi, I’m using the Rife them with Elementor, and it’s only breaking the to the top button.

I’ve already done going into Elementor -> Settings -> Advacned -> Load Font Awesome 4 Support and selecting yes and i’ve also went to Elementor ->?Site Settings -> Buttons -> Typography -> Family?and set it to default, Same results.

Please help me solve this, Thanks!
