On a 2 lead DFN it looks like there are no values you can enter for the toe,side, and heel ? Is this correct ? Also the default values for density level for the Flat No-Lead Side length <1.6MM are all the same for "L" "N" "M". Is this correct ?

On all "Bottom Only" terminals, LGA, CGA, BGA, 2, 3, 4 pin DFN, PSON, PQFN there is no Toe, Heel or Side. There is a periphery, meaning that whatever the value is, it's the same on all sides.
 
And once a component package is less than 1.6 mm the 3-tier system is thrown out and only one pad size is preferred.
