I just had exactly the same issue. Thank god I saw this or I would of spent ages trying to figure it out.

I had to rename my post type order to purchase_order and that fixed problem.

So weird.

I wasn’t using Custom Post Type UI plugin, I just had my post type hard coded with this…

<?php
class Types {

    /**
     * Types constructor.
     * @param null|int $id The Player ID to load
     */
    public function __construct ($id = null) {

        if(is_null($id)) {

            // on initial theme load, run various actions
            add_action('init', array ($this, 'action_init'));

        }

    }

    /**
     * Method to run on WordPress initialisation
     *
     * @uses init action
     * @see  https://codex.wordpress.org/Plugin_API/Action_Reference/init
     */
    public function action_init () {

        // register our post type
        $this->register_post_types();

    }

    /**
     * Returns an array of order labels available
     * to the labels post type
     *
     * @param null|string $key The specific label to load
     * @return array|string Array of labels or single
     * if key is defined
     */
    public static function order_labels ($key = null) {

        // create our array of labels
        $aLabels = array (
            'name'                  => 'Orders',
            'singular_name'         => 'Order',
            'add_new'               => 'Add order',

            'uploaded_to_this_item' => 'Uploaded to order',
        );

        // check if we are returning a single label
        if(!is_null($key) && array_key_exists($key, $aLabels)) {
            return $aLabels[$key];
        }

        // by default return all labels
