Category taxonomy

Hi everybody, i have to add category taxonomy to my video_podcasts post_type, and it’s okay, taxonomy added, but in admin panel when i’m creating new video_podcasts div where should be my categories is empty and looks like div with tags.
This is how i added taxonomy:

register_taxonomy('video_podcasts-category', array('Категории'), array(
			//'hierarchical' => true,
			'label' => 'Категории',
			'query_var' => true,
			'singular_label' => 'Категории',
			'rewrite' => true
		));

then

register_post_type( 'video_podcasts', array(
			'labels'          => $labels,
			'public'          => true,
			'show_ui'         => true,
			'capability_type' => 'post',
			'menu_icon'       => 'dashicons-video-alt2',
			'has_archive'     => true,
			'taxonomies'      => array(
				'video_podcasts-category'
			),
			'hierarchical'    => false,
			'supports'        => array( 'title', 'thumbnail', 'page-attributes', 'editor' ),
		) );

then

case 'video_podcasts-category':
				$term = wp_get_post_terms($id, 'video_podcasts-category');
				$term_type_products = array();
				foreach ($term as $item) {
					$term_type_products[] = '<a href="#">' . $item->name . '</a>';
				}
				echo implode(',<br>', $term_type_products);
				break;

then

function add_video_podcasts_columns( $columns ) {

		global $pageURLs;
		$new_columns['cb']              = '<input type="checkbox" />';
		$new_columns['title']           = _x( 'Заголовок подкаста', 'column name' );
		$new_columns['played_video_podcasts'] = _x( 'Прослушиваний', 'column name' );
		$new_columns['date']            = _x( 'Подкаст создан', 'column name' );
		$new_columns['image_video_podcasts']  = _x( 'Миниатюра', 'column name' );
		$new_columns['video_podcasts-category'] = _x('Категории', 'column name');

		return $new_columns;
	}

why it looks like div for tags?
