Max it's very easy..don't sweat!..it's the difference between "sample" and "population"..pay attention! Like in other areas as well such as standard deviation also treats sample and population differently by considering n-1 for sample and n for population so the same difference is here n+1 for population and n for sample..Makes sense?
