The template is useless since the guest hasn't asked for a quite room, it's a booking.com internal error that will be fixed soon
In extranet, navigate Inbox> booking.com messages and in the right column you will find a phone number of support and your local manager

This is a bug. The customer service of bdc said it would be fixed as soon as possible
