function custom_add_another_preprocess_field_multiple_value_form(&$variables) {
  foreach (Element::children($variables['element']) as $child) {
    $child_element =& $variables['element'][$child];

      if (isset($child_element['#custom_add_another_value']) && isset($variables['element']['add_more']['#value']) && $variables['element']['add_more']['#value'] != t($child_element['#custom_add_another_value'])) {
        $variables['element']['add_more']['#value'] = t($child_element['#custom_add_another_value']);
