WooCommerce – Losing add-ons/variations when Ordering Again

I really need help with WooCommerce! The products in the store have add-on options a customer can add. The ordering process goes fine but if a customer wants to reorder, WooCommerce isn’t adding the variations/add-ons to the new order. I’ve looked at the code and it plainly says “Load all product info including variation data” and the update said there was a fix applied but it still doesn’t work.

This is the code I am looking at for the “Order Again” section:

* Place a previous order again.
	 */
	public static function order_again() {

		// Nothing to do
		if ( ! isset( $_GET['order_again'] ) || ! is_user_logged_in() || ! isset( $_GET['_wpnonce'] ) || ! wp_verify_nonce( $_GET['_wpnonce'], 'woocommerce-order_again' ) ) {
			return;
		}

		// Clear current cart
		WC()->cart->empty_cart();

		// Load the previous order - Stop if the order does not exist
		$order = wc_get_order( absint( $_GET['order_again'] ) );

		if ( empty( $order->id ) ) {
			return;
		}

		if ( ! $order->has_status( 'completed' ) ) {
			return;
		}

		// Make sure the user is allowed to order again. By default it check if the
		// previous order belonged to the current user.
		if ( ! current_user_can( 'order_again', $order->id ) ) {
			return;
		}

		// Copy products from the order to the cart
		foreach ( $order->get_items() as $item ) {
			// Load all product info including variation data
			$product_id   = (int) apply_filters( 'woocommerce_add_to_cart_product_id', $item['product_id'] );
			$quantity     = (int) $item['qty'];
			$variation_id = (int) $item['variation_id'];
			$variations   = array();
			$cart_item_data = apply_filters( 'woocommerce_order_again_cart_item_data', array(), $item, $order );

			foreach ( $item['item_meta'] as $meta_name => $meta_value ) {
				if ( taxonomy_is_product_attribute( $meta_name ) ) {
					$variations[ $meta_name ] = $meta_value[0];
				} elseif ( meta_is_product_attribute( $meta_name, $meta_value[0], $product_id ) ) {
					$variations[ $meta_name ] = $meta_value[0];
				}
			}

			// Add to cart validation
			if ( ! apply_filters( 'woocommerce_add_to_cart_validation', true, $product_id, $quantity, $variation_id, $variations, $cart_item_data ) ) {
				continue;
			}

			WC()->cart->add_to_cart( $product_id, $quantity, $variation_id, $variations, $cart_item_data );
		}

		do_action( 'woocommerce_ordered_again', $order->id );

		// Redirect to cart
		wc_add_notice( __( 'The cart has been filled with the items from your previous order.', 'woocommerce' ) );
		wp_safe_redirect( WC()->cart->get_cart_url() );
		exit;
	}

Any help or direction is greatly appreciation!
