We did changes to the WooCommerce checkout to prevent showing any prices, and we added custom fields to the checkout, and we hide the additional information field. It works all the only problem in the order confirmation e-mail to the customer the table with the products and is showing a row underneath the products with this Symbol: ?>.
I can not find where this is coming from, probably there would usually the "additional information" being displayed?

Any idea which WooCommerce templates I would need to change?
I tried to modify the order-details.php and the order-item-details.php but without any success.
