Selected booking dates not showing up on woocommerce invoice order invoice

Hi,

We use this plugin with for woocommerce product page.
When customer selects the start and end date and click on checkout, they are then taken to woocommerce checkout form where they fill out rest of the information and complete the order.
Question I have, why is the woocommerce order and woocommerce purchase invoice does not show the dates selected by the customer?

Your kind reply at the earliest is really apprecited. Thank you.
