Problem connecting with Booking.com - multiple blockers but room is available!

Hello! I've connected NOBEDS with Booking.com, but now my calendar in Booking.com shows "multiple blockers" in the whole calendar and it not available on the site. However, I have it set, with the correct price in NOBEDS, and clicked the sync with Booking.com button multiple times.

Why is NOBEDS not sending availability to Booking.com?
