Tracking display does not show

I have been using the AST for a while and it has worked fine when entering the tracking number inside the order, client have got the tracking info in the tracking display in their emails.

Now I noticed that the tracking display is gone on my emails, I enter the email editor and all settings is as it was – but the tracking display is gone. Have tried to do some editing but I cannot get the display back.

I have tried to delete and reinstall AST, no luck.

Anyone?
