Jetpack Related Posts and Custom Posts Type doesn't work.

Hello! Using translator. Sorry for my mistakes.

I created a new posts type:

$args = array(
			'labels'              => $labels,
			'public'              => true,
			'show_in_menu'        => true,
			'menu_position'       => 6,
			'menu_icon'			  => 'dashicons-universal-access-alt',
			'supports'            => array('title', 'thumbnail', 'editor', 'comments'),
			'taxonomies'          => array('category', 'post_tag'),
			'rewrite'             => array('slug' => 'skins'),
			'query_var'           => true,
		);
		register_post_type('skins_type', $args);

functions.php:

function allow_my_post_types($allowed_post_types) {
	$allowed_post_types[] = 'skins_type';
	return $allowed_post_types;
}
add_filter( 'rest_api_allowed_post_types', 'allow_my_post_types' );

See page: http://minemik.ru/skins/skin-dzhudi-khops-iz-zveropolisa/
and nothing appears.

If you look at the page code, and there you can see the text “or similar entries,” but they are not.
