Double Booking (Bug?)

Hello guys, im having a bit of a trouble here, because for a room that we only have 1 available, we are sometimes getting double reservations for the same night both on booking.com 

I made sure that in available rooms it says 1 in the calendar but still i get 2 net bookings right in the space below.


two net bookings on a single room, can to me only happen if there is a misconfiguration by you on the room itself.

check the count on that room, and also the bed option.
