add Social Icons to header

my icons show up in layout-editor – icons, but i can’t select them in social icons dropdown menu.

i added this code to the very end of functions.php

add_filter('avf_default_icons','avia_add_custom_icon', 10, 1);
function avia_add_custom_icon($icons)
{
$icons['icon1']	 = array( 'font' =>'fontello', 'icon' => 'ue800');
$icons['icon2']	 = array( 'font' =>'fontello', 'icon' => 'ue802');
return $icons;
}

add_filter('avf_social_icons_options','avia_add_custom_social_icon', 10, 1);
function avia_add_custom_social_icon($icons)
{
$icons['Icon1'] = 'icon1';
$icons['Icon2'] = 'icon2';
return $icons;
