Products Not Showing In Shipment Notifcation

With our upgrade to the latest version of CS-cart the list of products is completely empty in the shipment notification email.

I am looking in

mail / templates / shipments / shipment_products.tpl and it must be a problem with the this loop:

{foreach from=$shipment.items key="hash" item="amount"}

So i am guessing the shipment.items list is empty. Any ideas what can cause this?

Try to print the whole $shipment array and check if it has necessary data

{$shipment|fn_print_r}
