single-listing.php and archive-listing.php – Not seeing code to change

Hi,
In the quick start guide, the instructions describe creating the single-listing.php and archive-listing.php files, which I’ve done. I don’t see the code your instructions say to find and replace however. Am I just missing it?

I’m using the Everett/Builder theme. Perhaps it’s not necessary with this theme?

Before I copied the single.php and archive.php file and renamed to single-listing.php and archive-listing.php, and uploaded, the listing page looked like the screenshot with all the details and the map. Then when I uploaded those, now they only show up like little blurbs, no details, second screenshot.

What am I doing wrong? I want it to be like the one with the details and the map, although layout wise you can see it has some problems.

Thanks in advance
