Add {shipping_provider} and {tracking_id} into the templates

Hi, I’m using the Plguin “Germanized” for shipping. The Plugin is able to put informations like {shipping_provider} and {tracking_id} into the standard Woocommerce emails sent to the customer. see attachment 1
Now I try to integrate these informations into the nice new email templates, but it doesn’t work. see attachment 2
How do I get this working?
