Tracking number not displaying on emails

Hi
I am unable to get the tracking number to display on the sipped emails to customers.

When I edit the layout in the “Launch Customiser” I select a order and the selected display before the order details and the sample displays fine.

I try a test order and enter shipping information and the resulting email shows no tracking information at all. The entire table containing the information is missing.

Tracking Information
Provider Tracking Number Shipped Date
Australia Post M2G0001473 January 13, 2020

The above was from the customiser and this is missing in total on the test emails.

Please tell me how to fix this.
Johanne
