I am having this same problem with the lastest version, however none of the key binds work so I can not access the squad menu or the console, the only things I have access to use mcc itsself and sometimes the squadleader pda
Basically I play single player a lot so I use team switching however when I switch to another group leader the previous group leader will order his group to disembark vehicles they are in or order them to board a vehicle several kilometers away, basically I just need to be able to prevent the ai group leader from issuing orders to the team if that is possible?
