When changing the address from 2->3 @ the 2nd floor and 3->2 @ the 3rd floor the problem then changes to the 3rd floor. The elevator is 4 stops front and rear openings at all the floors

If I remember when i put a call in from the conoller service menu it opened the door and registered an up call at the 2nd floor (but I am not sure). I will double check this
