Looks like you might have some CSS in there adding in the icons via CSS. We stopped that approach and are just using the normal XF approach for the icons. Check your extra.less for this:
.p-linkList-changeStyle a:before
/* Style switch icon in Footer START */
.p-linkList-changeStyle a:before, .p-linkList-changeWidth a:before, .p-linkList-changeLanguage a:before, .p-linkList-toggleSidebar a:before
{
.m-faBase();
display: inline-block;
margin-right: 2px;
}
.p-linkList-changeStyle a:before { .m-faContent(@fa-var-paint-brush); }
.p-linkList-changeWidth a:before { .m-faContent(@fa-var-sliders-h); }
.p-linkList-changeLanguage a:before { .m-faContent(@fa-var-globe); }
.p-linkList-toggleSidebar a:before { .m-faContent(@fa-var-toggle-on); }
/* Style switch icon in Footer END */
