Wrong # of posts in Admin (custom post type)

Hi,

I have a custom post type. And have given the subscriber following capabilities

$role_object->add_cap( 'read_customposttype' );
$role_object->add_cap( 'edit_customposttype' );
$role_object->add_cap( 'publish_customposttype' );
$role_object->add_cap( 'delete_customposttype' );

This works perfectly. I also have following edit.php hack:

function mypo_parse_query_useronly( $wp_query ) {
    if ( strpos( $_SERVER[ 'REQUEST_URI' ], '/wp-admin/edit.php' ) !== false ) {
        if ( !current_user_can( 'level_10' ) ) {
            global $current_user;
            $wp_query->set( 'author', $current_user->id );
        }
    }
}
add_filter('parse_query', 'mypo_parse_query_useronly' );

This also works perfectly. But there is an issue regarding number of posts in edit.php in admin panel. This number shows the total of all posts. I want to show the number of posts for owner only.

Somebody can help me? Is there anything else you need to know about my code?
