Where do i format the listing page?

Here is what my listing page looks like in version 9 – https://test.mustangtraderonline.com/mustang-for-sale/2007-shelby-gt-mustang-low-miles/. i can’t find where this is formatted. it doesn’t seem to be using the admin area/design setup/page builder “listing page” format.. Also if i edit the ‘Template’ called ‘Listing Page’, that doesn’t seem to be it either. I’d like to change the format of this page but don’t know where.
