comment admin for custom post types

Hi there,

I registered a custom post type with option to comment:

$args = array(
				'labels' => $labels,
				'public' => true,
				'publicly_queryable' => true,
				'show_ui' => true,
				'query_var' => true,
				'menu_icon' => null,
				'rewrite' => array('slug' => __('mycpt', 'mycpt')),
				'capability_type' => 'post',
				'hierarchical' => false,
				'menu_position' => null,
				'supports' => array(
									'title',
									'editor',
									'comments'
									)
				);

	register_post_type( 'mycpt' , $args );

So it’s commentable. Works fine in front end.

But the posted comments are not shown in admin under “comments”. They exist and i can find them in db via phpmyadmin, but for some unknown reasons they are not listed in the admin. Is there an option for “dont show comments related to a custom post type” or something like this?

thx
