1) The logistics cost when raising formations oustide of your SHQ tile is currently not including the unit's supplies. The supplies are transported for free.
For example, I have an MG battalion, which requires 25 logistics points in the raise formation screen. Because 5 times the weight of 5 is 25.
However, when I raise it, it starts with full supplies of 10 food and 50 ammo, which actually raise its weight to 85 for strategic move normally.

2) The number for the logistics cost doesn't update when you unselect some of the unit types. This one is just a display bug as far as I can see.
