Awesome font issues using Elementor

Hi, As many others, I do have some issues with my awesome font. I'm using Elementor for all my pages. In the header menu on my desktop page, the icons were changed. I did manage to change them back to arrows, but it does not work on the mobile version. The mobile version has no hamburger icon and no arrows in the dropdown toggle. I did manage to change this in the Chrome inspection tool, but it does stick if I use the code in additional CSS after saving. https://snowboardarlberg.com/ Thanks
