bug on enfold 4.0.3

on this thread there was a question to substitute a shortcode in parent theme .

On Versions before the old code do the trick:

add_filter('avia_load_shortcodes', 'avia_include_shortcode_template', 15, 1);
function avia_include_shortcode_template($paths)
{
  $template_url = get_stylesheet_directory();
      array_unshift($paths, $template_url.'/shortcodes/');

  return $paths;
}

Then you only have to create a new shortcode or a copy of the original and change code in it. The copy of the shortcode will overwrite the original!
But now this doesn’t have any influence – allthough the new child-theme shortcodes are visible in Dashboard – Appearance – Editor. The Changings have no effect!

Any Advices to change that back to “old school”
