Hello,
V2 brings in a lot of changes, but the basics are still the same.
For Supreme the featured image, page title and subtitle are set in the page itself. You can still use this doc: https://wpgeodirectory.com/docs/supreme-directory-overview/
It looks like you are using the Location Description, which text is set in the Location Manager: https://wpgeodirectory.com/docs-v2/addons/location-manager/#location-data
The listings shown in rows, each one is an individual listing, and the data is entered through a form in the frontend or backend editor. Generally speaking individual listings are not edited with a builder (usually). Instead the information is assembled in the form.
GDV2 introduces templates. You can see this page to learn more about how those listings are created (visually) with the Archive Item template. https://wpgeodirectory.com/docs-v2/geodirectory/page-design/
We are happy to answer your questions here. However, if you would like some hands on help on your site we encourage you to contact a GD Expert that can help you with tailoring your site to meet your expectations: https://geodirectoryexperts.com/experts/
