Fa drop down icon not laoding on dekstop

Font Awesome icons not loading.

class=”nav-arrow fa fa-angle-down” showing as box with question mark.

Note, i have checked the box regrading fa in the settings for elementor & added the code as advised(https://docs.oceanwp.org/article/603-icons-missing-or-showing-up-as-squares). However, this made the problem effect mobile too so i removed code and disabled option.
