Change "All" label in Portfolio grid

here is my child theme’s folder.

If I leave this way I have blank page in the frontend :(

Here is my child functions.php content:

<?php

/*
add_action( 'wp_enqueue_scripts', 'enqueue_parent_theme_style' );
function enqueue_parent_theme_style() {
    wp_enqueue_style( 'parent-style', get_template_directory_uri().'/style.css' );
}
*/

/*
 * aggiungo funzione per trasformare All in All Properties
 */
add_filter('avf_portfolio_sort_first_label','new_first_label');
function new_first_label() {
$first_item_name = "All Properties";
return $first_item_name;
}

here is my child style.css:

/*
Theme Name:     Wedding Planners in Tuscany
Theme URI:      http://www.alohamoku.it
Description:    Tema Child di Enfold per Wedding Planners in Tuscany
Author:         Nicola Strumia
Template:       enfold
Version:        0.1
*/

@import url("../enfold/style.css");

ok I removed (anyway they were unaccessible for wp, because they were named “-full-functions.php, -config-templatebuilder).
I think the error was in my child functions.php.
Now all works.

Thanks!
