Hello Heather,
Thanks for contacting WPDM Support forum.
You have to use template tag to show that. The available template tags can be found here. the template tag should be added to the link template that you will use. The template tag [create_date]
returns The Publish Date of a Package
As you are using free version, you can’t add template tag directly. You have to follow the number 3
point from here.
Thanks
Tanvir
