Hi! or should I say g'day!
I believe the issue you are having is an easy fix--you will need to make a "Seller Details" profile so that your shipping/payment/about us/etc information will appear in the appropriate sections of the template. After you have created and saved your Seller Details profile, you will then see where to select it on the Lister (next to where you select the template.)
To create the profile check out this FAQ Seller Details
If that doesn't solve your problem, please let us know.
Thanks!
