I've solved the issue. Problem was I had spaces in the class names. But now, when i place the orbat module down, im only getting Task Force Athena icon, which is sync'd to a unit, NATO,EU flags, but no sub unit.
For my NATO marker, which isn't sync'd to a unit and shows up on the map.
missionConfigFile >> "CfgORBAT" >> "TaskForceAthena" >> "Nato"
missionConfigFile >> "CfgORBAT" >> "TaskForceAthena"
But when I want to place my NATO BattleGroup. not sync'd to a player. Doesn't show up on my map.
missionConfigFile >> "CfgORBAT" >> "TaskForceAthena" >> "NatoBG"
missionConfigFile >> "CfgORBAT" >> "TaskForceAthena"
