Using hierarchical with Cutom Post Type

I have everything the way I want it to be. I made categories using the custom taxonomy and added columns on post screens so that you can see the attributes for each post at a glance. Like the description of each post, the custom field value of each. But when I set the hierarchical value to true, the values on the columns disappear. I just want to be able to use the orderby=menu_order.

add_action('init', 'programming_register');

function programming_register() {

	$labels = array(
		'name' => _x('Programming', 'post type general name'),
		'singular_name' => _x('Programming Item', 'post type singular name'),
		'add_new' => _x('Add New', 'programming item'),
		'add_new_item' => __('Add New Programming Item'),
		'edit_item' => __('Edit Programming Item'),
		'new_item' => __('New Programming Item'),
		'view_item' => __('View Programming Item'),
		'search_items' => __('Search Programming'),
		'not_found' =>  __('Nothing found'),
		'not_found_in_trash' => __('Nothing found in Trash'),
		'parent_item_colon' => ''
	);

	$args = array(
		'labels' => $labels,
		'public' => true,
		'publicly_queryable' => true,
		'show_ui' => true,
		'query_var' => true,
		'menu_icon' => get_stylesheet_directory_uri() . '/article16.png',
		'rewrite' => true,
		'capability_type' => 'post',
		'menu_position' => null,
		'hierarchical' => false,
		'orderby' => 'menu_order',
		'supports' => array('title','editor','thumbnail','page-attributes')
	  ); 

	register_post_type( 'programming' , $args );
}

add_action( 'init', 'create_schedule' );
function create_schedule() {
 $labels = array(
    'name' => _x( 'Schedule', 'taxonomy general name' ),
    'singular_name' => _x( 'Schedule', 'taxonomy singular name' ),
    'search_items' =>  __( 'Search schedule' ),
    'all_items' => __( 'All schedule' ),
    'parent_item' => __( 'Parent Schedule' ),
    'parent_item_colon' => __( 'Parent Schedule:' ),
    'edit_item' => __( 'Edit Schedule' ),

  register_taxonomy('Schedule','programming',array(

}

add_action("manage_posts_custom_column",  "programming_custom_columns");
add_filter("manage_edit-programming_columns", "programming_edit_columns");

function programming_edit_columns($columns){
  $columns = array(
    "cb" => "<input type=\"checkbox\" />",
    "title" => "Programming Title",
    "description" => "Description",
    "time" => "Program Time",
    "Schedule" => "Schedule",
  );

  return $columns;
}
function programming_custom_columns($column){
  global $post;

  switch ($column) {
    case "description":
      the_excerpt();
      break;
    case "time":
      $custom = get_post_custom();
      echo $custom["program_time"][0];
      break;
    case "Schedule":
      echo get_the_term_list($post->ID, 'Schedule', '', ', ','');
      break;
  }
}

This is my code. Thanks for your help.
