Add Listing help

Hi, I am a new member so just learning about GD and the add-ons. I read thru the docs and forums. I am unsure how the add listing page works. I installed all GD add-ons, GD theme and activated GD Child theme. I imported dummy data and have it show. When I goto add-listing page in backend it has no shortcode or any code, yet the website is displaying an add-listing page with several fields to complete. I filled in the required data to test it and after I click review listing it takes me to the home-page without previewing the new entry. Also how do I change the form data inputs to show on add-listing page? Is there a more detailed manual (doc) for theme settings and add-ons?
Thanks
