You can crow-bar a leader with a different "size" rating into a smaller unit in the editor, but once changed, they cannot go back again. Examples are Admirals Mitscher & (Ted) Sherman, who arrive as carrier captains, despite being ranked as, and designated as, task force level commanders. You can also put Chesty Puller in charge of a marine division - split it in 3, make him the "A unit" commander and reform the division. So I don't think that would cause the exe to default to a random pick.
So it is more likely something like changing the Vichy leaders' arrival date, if the nationality and rank are setup right. Try 411206 - if they are assigned to a unit in the scen file they won't actually turn up then.
