Can’t book same hours for different services

Hi,

I need to create reservation slots for different rooms (I used Services to create rooms). When I reserve a slot in a room, I see that those slots are booked for this room, but when I select another room, the time slots are simply missing (the ones I used for the other room). Capacity for each rooom is set to 1. Any idea where the problem might come from ?

Thank you
