Unwanted units in Ambient Combat

[kirkherbstreit 1]

There doesn't seem to be a topic regarding this anywhere...

Below is my script that I tried in ACM once today. So far the module has been pretty good at spawning a lot of units that I didn't ask for in the script, as far as I can see. There have been many BMP-3s, Helicopters, Su-25s, and such. However there have also been several units that I did ask for. I don't know why the other units are spawning too, as air patrols are set to 0.

waitUntil {!isNil {BIS_ACM getVariable "initDone"}};  
waitUntil {BIS_ACM getVariable "initDone"};  
sleep 5;    
[1, BIS_ACM] call BIS_ACM_setIntensityFunc;  
[bIS_ACM, 500, 1200] call BIS_ACM_setSpawnDistanceFunc;  
[["BIS_US", "BIS_CZ", "BIS_GER", "BIS_UN", "BIS_TK_INS"], BIS_ACM] call BIS_ACM_setFactionsFunc;  
[0.1, 0.5, BIS_ACM] call BIS_ACM_setSkillFunc;  
[0.55, 0.85, BIS_ACM] call BIS_ACM_setAmmoFunc;  
["ground_patrol", 1, BIS_ACM] call BIS_ACM_setTypeChanceFunc;  
["air_patrol", 0, BIS_ACM] call BIS_ACM_setTypeChanceFunc;  
[bIS_ACM, ["US_RifleSquad", "US_WeaponsSquad", "US_TeamMG", "US_MotorizedSection", "US_DeltaPatrolHMMWV", "ACR_InfantryPatrol", "ACR_SpecialForcesPatrolLandRover", "KSKTeam", "TK_INS_Group", "TK_INS_Patrol", "TK_INS_Technicals", "TK_INS_MotorizedGroup", "UN_Patrol", "UN_MotorizedPatrol", "UN_MechanizedPatrolM113"]] call BIS_ACM_addGroupClassesFunc;

Are my units wrong?
