Hello jjchef,
In order for the other sections like "payment", "Shipping", etc. to show inside your listing you will need to create a "Seller Details Profile" which you can find at the "Profile" page. You will need to fill in the information you will want displayed for each of these sections then save the profile with a name you can remember. Once you are creating a listing you will get to the section of the page where you select a template once you have selected one and "Saved template to Listing" you will notice that to the right of that area is a drop down box with the words "Seller Details" in it. Click inside this area to view all the profiles that you have saved, select the one you wish to use. If you preview after this point you will notice the sections that you wanted filled in will be where you want them.
