Custom Social Icons Not Showing

Hi,

Added below code to functions.php file to add custom social icons,

// Register new icon as a theme icon
function avia_add_custom_icon($icons) {
	$icons['Groupware'] = array( 'font' =>'fontello', 'icon' => 'UF1A0');
	$icons['TeamViewer'] = array( 'font' =>'fontello', 'icon' => 'UE801');
	$icons['Messenger'] = array( 'font' =>'fontello', 'icon' => 'UF136');
	$icons['Wiki'] = array( 'font' =>'fontello', 'icon' => 'UF266');
	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['Groupware'] = 'Groupware';
	$icons['TeamViewer'] = 'TeamViewer';
	$icons['Messenger'] = 'Messenger';
	$icons['Wiki'] = 'Wiki';
	return $icons;
}
add_filter('avf_social_icons_options','avia_add_custom_social_icon', 10, 1);

But doesn’t show at Enfold Theme Options > Social Profiles dropdown menu.
Could you please advise?

Thank you,
-Leanne
