I don't know yet if this was a one time thing, or if it's a feature of the game. But I think I know how to unload units from an Army.
I had an army of 3 Riders, on the same tile as the army was about 5 other Riders, so I press 'J' to move all of the Riders, and as a Result all my Riders were moved, even those in the Army, but not the Army unit itself, so next turn I could load the Army with new units!
I will post again when I have tested this some more!
