To improve this fucntion you can use following code, to add in the file functions.php of your theme.

 

if( !function_exists('yith_customize_woocommerce_order_formatted_billing_address') ){
    function yith_customize_woocommerce_order_formatted_billing_address( $address ){
        if( function_exists('ywccp_get_custom_fields') ){
            $custom_billing_fields = ywccp_get_custom_fields( 'billing' );
            foreach ( $address as $key => $value ){
                if( array_key_exists( 'billing_' . $key, $custom_billing_fields ) ) continue;
                $address[$key] = ucwords(str_replace( '_',' ',$key )) . ': ' . $value;
            }
        }

        return $address;
    }
}
add_filter('woocommerce_order_formatted_billing_address','yith_customize_woocommerce_order_formatted_billing_address',10 );


if( !function_exists('yith_customize_woocommerce_order_formatted_shipping_address') ){
    function yith_customize_woocommerce_order_formatted_shipping_address( $address ){
        if( function_exists('ywccp_get_custom_fields') ){
            $custom_shipping_fields = ywccp_get_custom_fields( 'shipping' );
            foreach ( $address as $key => $value ){
                if( array_key_exists( 'shipping_' . $key, $custom_shipping_fields ) ) continue;
                $address[$key] = ucwords(str_replace( '_',' ',$key )) . ': ' . $value;
