Hello.
Probably you have inserted the shortcode for only “availability calendar” [bookingcalendar type=1 nummonths=1] instead of shortcode for booking form [booking type=1 nummonths=1]
Please open the page with booking form for editing, then remove the existing shortcode. After this switch from the “Visual” view mode to “Text” view mode your content editor. And then reinsert the Booking Calendar shortcode and test it.
You need to insert this shortcode:
[booking type=1 nummonths=1]
Please note, this shortcode [bookingcalendar type=1 nummonths=2] is only for showing availability calendar, without form, where you can not select the dates.
Please read more how easily insert booking form or availability calendar into a pages https://wpbookingcalendar.com/help/inserting-booking-form/ or how manually configure Booking Calendar shortcodes in content of your pages: https://wpbookingcalendar.com/help/booking-calendar-shortcodes/
Kind Regards.
