Hierarchical CPT

Hi. My CPT Producer don’t show the option to assign parents. Any idea how to fix this?

<?php

register_post_type(
	'producer',
	array(
		'labels'			 => array(
			'name'			 => 'Producent',
		),
		'description'        => 'Fairtrade producenter.',
		'public'             => true,
		'publicly_queryable' => true,
		'show_ui'            => true,
		'show_in_menu'       => true,
		'query_var'          => true,
		'rewrite'            => array( 'slug' => 'fair_producer' ),
		'capability_type'    => 'post',
		'menu_icon'			 => 'dashicons-exerpt-view',
		'has_archive'        => true,
		'hierarchical'       => true,
		'menu_position'      => 26,
        'taxonomies'         => array( 'category' ),
		'supports'           => array( 'title', 'editor', 'thumbnail', 'category', 'excerpt', 'page-attributes' )
	)
);

register_taxonomy(
	'producer_category',
	array( 'producer' ),
	array(
		'hierarchical'		 => true,
		'labels'			 => array(
			'name'			 => 'Kategorier',
			'singular_name'	 => 'Kategori',

		),
