Как удалить дубли прилепленных записей WP?

$sticky = get_option( 'sticky_posts' );
$args = array(
          'category__not_in' => array(1, 13, 14, 15, 18),
          'post_type' => array('post'),
          'publish' => true,
          'paged' => get_query_var('paged'),
          'posts_per_page' => 10,
          'ignore_sticky_posts' => 1,
	  'post__not_in' => $sticky
      );

      query_posts($args);
            
      while ( have_posts() ) : the_post();
        get_template_part( 'content', 'shortpost' );
      endwhile;

      wp_reset_postdata();
      navigation();
