i am just mentally picturing the problem.  The elevator comes to our 
floor, which is the top floor, and there's a button "A" on the rail to 
keep it from going too far.  There is another button "B" which tells the 
system that it's on the third floor, and is ready to be called to another 
floor because it's done moving around.  The button "A" is being triggered 
before button "B" and the elevator stops moving before it really "arrives" 
at the third floor.

When one goes in there and presses the 3 button again, the button bypasses 
the stop switch for long enough to run the motor enough to bump it up a 
quarter-inch until it presses button "B" telling the system it's arrived 
at the third floor and everything is okay.

It might not be as simple as adjustment however, because it could be that 
the capacitor or diode protecting the buttons' contacts from the inductive 
kick of the relay it triggers has failed to protect the button contacts, 
and the button needs to be replaced.  Only an elevator-repairfolk will 
have the exact correct replacement button, and really know how to adjust 

As much as I would be okay with getting covered in grease and mouse-shit 
trying to find both buttons and adjusting them, and hoping that the 
problem is only adjustment (which is slightly unlikely) i think it's 
probably better to have the repair made by the professional.  However if 
the landlord/property owner flat-out says that they'd rather us try to fix 
it first, we should go for it.

But at this point, with the elevators' behavior properly sussed out (the 
note on the door is excellent) it should be easy for a repairperson to do 
the job without wasting too much time.
