@chouby Also, please remember that WPML now allows only single key name to register all theme mods. It means no need to add theme mods one by one.

    <admin-texts>
        <key name="theme_mods_themename">
        </key>
    </admin-texts>  

In your code, you should also check if there is no sub key, if the it is a “theme_mods_***” then add all theme mods available.

Something like this;

	protected function translate_strings_recursive( $values, $key ) {
		$children = $key->children();
		if ( count( $children ) ) {
			foreach ( $children as $child ) {
				$attributes = $child->attributes();
				$name = (string) $attributes['name'];
				if ( isset( $values[ $name ] ) ) {
					$values[ $name ] = $this->translate_strings_recursive( $values[ $name ], $child );
				}
			}
		} else {

//$values = pll__( $values );
if(is_array($values)){
 $mods = get_theme_mods("themename");
  foreach{
    //regiter
   }
}

		}
		return $values;
	}
