I've discovered whilst playing Zeus that when multiple units have been selected, double-clicking and editing their behaviour (formations, combat mode, stances, etc) results in only one unit being affected instead the entire selected group. For example, if I click and drag to select Alpha 1-1 and Alpha 1-2, and double-click to change their formations to Line, only Alpha 1-1's behaviour would change, with Alpha 1-2 being unaffected. Additionally, trying to edit several unit's waypoints at once yields the same result - with only one unit's behaviour changing, with the rest being unaffected.

I've tested the game without mods, and the problem still persists. The issue does not occur in the Legacy build however, which leads me to believe that this bug is the result of the S.O.G Prairie Fire Update 1.1, or one of its smaller updates.
