Hello.
We are sorry about your experience. Please note, in the Booking Calendar Free version possible to configure only the simple booking forms without knowing any HTML. You just need to enter the titles and types of your booking form fields and save it. While it is simple, it is limited in capability to configure the different structure of the booking forms, like several fields in one row, creation of different custom booking forms, etc..
If you need to create and customize the several different custom booking forms it is possible in the paid versions and such customization possible to-do only in advanced booking form configuration, which is visible in your screenshot.
Such Advanced booking form configuration uses the standard HTML for definition of booking form structure, and shortcodes for form fields. The shortcodes possible to generate by using the shortcode generator at the right side of your page, which is visible in your screenshot at right side.
Such way of configuration booking form give you flexibility to configure almost any type of booking form. But from other side it is means that you need to know HTML, at least some basic HTML tags. I can imaging if you do not know the HTML, then it is big challenge to configure it.
In case if you do not know HTML but still want to use the several custom booking forms in advanced booking form configuration you can send to us the fields and titles that you need and we can create configuration of such booking form(s)s for you.
Because this functionality available only in the paid versions and not relative to the free version, please send such info (description about the form fields for your booking form) to support @ wpbookingcalendar.com or post it here https://wpbookingcalendar.com/support/
This forum is only about support of Booking Calendar Free version.
Kind Regards.
