minimum reqirements on listing question

[hairbear]

i have noticed in several list that i have tried to create that the minimum requirements never change.
flames of war lists , in the rle book it states that an army of 600 points only requires 1 platoon.
simular to this the warhammer 40k combat patrol list does not require a hq unit,

in both of the above lists the program reverts to a minimum 1 hq and 2 platoon/troop choices.
my question is this to do with the way that the data files are set up and you get no variance between the standard and special rules set or a feature that has been missed by the developers.
