Dear Michale,
There is no need to add the fields to the layout, this is only used to build the default Meta HTML that you will be replacing anyway. Just choose the post types and paste the code above in the layout Meta HTML. The actual layout of each row is controlled by 2 View Template in my example: "Company row template" and "Company row template"
Please let me know if you are satisfied with my answer and if I can help you with any other questions you might have.
Regards,
Caridad
