Booking form is not displayeBooking form is not displayed on d on the hotel page

I have everything installed and set up correctly. However, it does not show me any booking option on the hotel room product page. No date selection etc. What could be the reason for this? Here is the example page

https://www.roterhirsch.com/hotelanzeige/ferienwohnung-1/

We use the Oxygen Page Builder with Woocommerce integration as theme. Is there a shortcode I can use to display the booking?
