New order fields are not displayed in the email and admin panel. How to fix?

Question

WooCommerce

Field 1, Field 2.... are naturally displayed in the admin panel and the letter, but the value from the form is not pulled up there.
I indicated the correct id. Tell me where I could make a mistake?
(Fields added via plugin)

add_action( 'woocommerce_admin_order_data_after_shipping_address', 'custom_field_display_admin_order_meta', 10, 1 );

function custom_field_display_admin_order_meta($order){
    echo '<p><strong>'.__('Поле 1').':</strong> ' . get_post_meta( $order->id, 'additional_name', true ) . '</p>';
    echo '<p><strong>'.__('Поле 2').':</strong> ' . get_post_meta( $order->id, 'additional_phone', true ) . '</p>';
    echo '<p><strong>'.__('Поле 3').':</strong> ' . get_post_meta( $order->id, 'shipping_otkritka', true ) . '</p>';
    echo '<p><strong>'.__('Поле 4').':</strong> ' . get_post_meta( $order->id, 'shipping_adress', true ) . '</p>';
    echo '<p><strong>'.__('Поле 5').':</strong> ' . get_post_meta( $order->id, 'shipping_date', true ) . '</p>';
