Icon List Child Theme doesn't change the color

Hi all!

I created the child theme as indicated here,
I exported/imported the config data from the parent to child theme, but now the Icon List doesn’t show properly, it doesn’t change the color from gray to orange as it is supposed to be.
When I added this code to functions.php (as recommended on the link above), the icons appeared smaller and also didn’t change the color, they stay gray.

function wp_change_aviajs() {
   wp_dequeue_script( 'avia-default' );
   wp_enqueue_script( 'avia-default-child', get_stylesheet_directory_uri().'/js/avia.js', array('jquery'), 2, true );
}
add_action( 'wp_print_scripts', 'wp_change_aviajs', 100 );

Could you help me please?
