Hello,

You can fix that by adding the following style at Bakery > Custom Code > Custom CSS:

.vu_tb-list > li.menu-item-has-children > a:after,
.vu_main-menu > ul > li.menu-item-has-children > a:after,
.vu_main-menu ul.sub-menu li.menu-item-has-children > a:after,
.widget_nav_menu .menu > li > a:after,
.vu_blog-post.vu_bp-type-link:before,
.vu_blog-post.vu_bp-type-quote .vu_bp-quote:before,
.vu_list-with-icon[data-font="FontAwesome"] li:before,
.vu_dropdown:after,
.woocommerce-product-search:after {
    font-family: "Font Awesome 5 Free" !important;
    font-weight: 900 !important;
}
.vu_latest-tweets ul li:before {
    font-family: "Font Awesome 5 Brands" !important;
    font-weight: 400 !important;
}

Kind regards,
