Importing custom icon to social profiles

I am having trouble importing my custom icon into the social icons. It imports to the theme fine but does not appear in the social icons menu.

// Register new icon as a theme icon
function avia_add_custom_icon($icons) {
$icons['realself'] = array( 'font' =>'realself', 'icon' => 'E801');
return $icons;
}
add_filter('avf_default_icons','avia_add_custom_icon', 10, 1);

// Add new icon as an option for social icons
function avia_add_custom_social_icon($icons) {
$icons['Icon Label'] = 'realself';
return $icons;
}
add_filter('avf_social_icons_options','avia_add_custom_social_icon', 10, 1);

I have looked through other threads and no solutions are working so there must be something I’m missing. I have tried icon codes E801, UE801, 0xUE801
