wordpress woocommerce interfax sends fax with a missing field - php

Question

I am not a php programmer, and it takes me forever to figure out why. So hopefully SO could help me out. Basically, I installed a woocommerce plugin called interfax-woocommerce, which is used to send order completion email to fax number. On the documentation, it says the plugin uses order completion template to send the fax. It does include everything on the order email template except leaving the order note field out. I believe it must have something to do with the plugin. maybe it passes the order array without including that particular order note field? I can not figure out why and how to fix it. Below is the source code of interfax plugin

Here is an example of adding the customer's note (which is the order post's "excerpt") to the bottom of all emails:
add_action( 'woocommerce_email_after_order_table' , 'so_28333042_add_customer_note' );
function so_28333042_add_customer_note( $order ){
$post = get_post( $order->id );
if( $post->post_excerpt != '' ){
echo "<strong>Customer Note:</strong><br/>" . wp_kses_post( $post->post_excerpt );
}
}
The woocommerce_email_after_order_table hook is definitely available in WooCommerce 2.3, but I think it is available in 2.2+ as well.
Alternatively, you could copy the customer-completed-order.php template into your theme and work directly on it.
