Quote email and pdf do not show $valid_until date

I updated the quote eMail template and details to include the $valid_util date.
However, neither the template nor the pdf show this information.
How do I get this information to show up on the quote PDF/eMails.
Also I created another post about changing the word Quote to Estimate and the ‘View Quote’ button also does not display the word estimate after the change.

This is what is shown in the email body and subject: To view estimate EST-009022 expires $valid_until, click the link below.


It’s possible $due_date will work but $valid_until should be supported.
