Yes,  it is common, but it can most likely be cured.  The problem is 
likely that
the heater valve is not closing all the way, which is caused by an 
out of adjustment
heater valve control wire.  The wire is moved by the hot<->cold 
slider in the HVAC
control unit.  Anyway, check which direction is 'cold' at the valve 
by moving the
slider and checking which way the little arm at the valve goes. 
After figuring this
out, push it the rest of the way by hand, and it's likely to go just 
a tiny bit further.
This will finally shut off the flow of hot coolent to your heater 
core and you'll
stop getting heat out of the center vents.  My car suffers from the 
same problem. :(
