Do you have multiple overlapping zones? (maybe in layers that are turned off).
Overlapping zones may confuse things I think.
I did a little test (with door 24) and it seems the 'Related zone' is not affected by the 'Door belongs to the zone into which it opens' parameter.
The related zone seems to be the one that the door swings into.
The 'From Room' & 'To Room' fields are affected by the 'Door belongs to...' parameter.
But it seems to me they are back to front.
I my example with that parameter 'ON', door 001 says it is from zone 01.
That door opens into zone 02, so I would have thought it should be from zone 02 - the zone into which it opens.
I don't think I would be relying on the from/to room fields.
It seems to me that the related zone is more reliable - but maybe further testing is needed.
