How can I set up a maximum length of stay restrictions?

Following the tutorial from this page https://partner.booking.com/en-gb/help/reservations/how-can-i-set-minimum-or-maximum-length-stay-restrictions, I can see only minimum stay options.

Thank you.

Updates: here's a video where you can setup a maximum length of stay restrictions:https://youtu.be/_Qa4HPkrRpk

In my case, there's no button "Bulk Edit" as the hotel is using a channel manager. The issue has been solved by BDC support. Thanks.
