Edit role capabilities for multiple custom post types

I was able to get the first CPT registered and added to administrator and editor roles, but for some reason doing the same thing for a 2nd CPT isn’t working and I can’t figure out why.

The registration

function register_clubs_post_type() {
  $labels = array(
    'name' => __( 'clubs' ),
    'singular_name' => __( 'club' ),
    'add_new' => __( 'Add club','club' ),
    'add_new_item' => __( 'Add New club' ),
    'edit_item' => __( 'Edit club' ),
    'new_item' => __( 'New club' ),
    'view_item' => __( 'View club' ),
    'search_items' => __( 'Search clubs' ),
    'not_found' => __( 'No clubs Found' ),
    'not_found_in_trash' => __( 'No clubs In Trash' ),
    'parent_item_colon' => ''
  );

  $args = array(
    'labels' => $labels,
    'public' => true,
    'publicly_queryable' => true,
    'show_ui' => true,
    'query_var' => true,
    'has_archive' => true,
    'supports' => array( 'title','editor','excerpt','custom-fields','thumbnail' ),
    'rewrite' => array('slug' => 'clubs','with_front' => false),
    'hierarchical' => false,
    'capability_type' => 'clubs',
    'map_meta_cap' => true
  ); 

  register_post_type( 'clubs', $args );
}
add_action( 'init', 'register_clubs_post_type',0 );

The role editor of the old CPT that worked like a charm

if ( is_admin() && '1' == $_GET['reload_caps'] ) {
		$administrator     = get_role('administrator');
		$artists_relations = get_role('artists_relations');
		$editor = get_role('editor');

		$administrator->add_cap( 'assign_custom_taxes' );
		$artists_relations->add_cap( 'assign_custom_taxes' );
		$editor->add_cap( 'assign_custom_taxes' );

		foreach ( array('publish','delete','delete_others','delete_private','delete_published','edit','edit_others','edit_private','edit_published','read','read_private',"manage_categories") as $cap ) {
			$administrator->add_cap('{$cap}_artists' );
			$artists_relations->add_cap( '{$cap}_artists');
			$editor->add_cap( '{$cap}_artists' );
		}

Modified for this new registration (artist removed completely)

foreach ( array('publish','delete','delete_others','delete_private','delete_published','edit','edit_others','edit_private','edit_published','read','read_private',"manage_categories") as $cap ) {
			$administrator->add_cap('{$cap}_clubs' );
			$artists_relations->add_cap( '{$cap}_clubs');
			$editor->add_cap( '{$cap}_clubs' );
		}

Why would one work and the other doesn’t? Does anyone know how I can get the roles edited for this CPT?

If i comment out the capability_type line it shows up just fine, but with it active no role can see it.
