Unit rank for custom units

[anon53]

I am not sure where this belongs.. its to do with the game in terms of ... program? and not model or really the map.. could be the editor's settings that apply to this i hope.
I am trying to figure out how the units are ranked when you "grab" them.. or group them when you click and drag in the game.

i have 2 custom units,

F1 unit, the first guy is displayed second when draged with the F2 unit.

i cant figure out why this is soo, even in the rank formation F2 is second.. but its grabed and deemed first.
can someone explain why this is? (assuming i explained well enough)

There is a formation number - which organises who stands at front, back etc when yuo move a group. That may organise the units in the group display too.
