Do you mean you have a 'Main' zone for the entire uni.
ten overlaying this you have an 'Entry' zone and a 'Bedroom' zone?
Archicad does not like overlapping zones very much.
Abutting zones are fine as you have 'From zone' and 'To zone' which is based on the door swing direction and 'Related zone' which I think is the zone the door object actually is placed in - I think that has to do with the placement (reveal) side of the door as you place it.
But as soon as you have overlapping zones, it all gets a little murky.
