missionCommands.removeItem() Bug

Under certain circumstances, the script command missionCommands.removeItem() removes more items than it is supposed to do.

Observe the following script which is run for a MP test mission for 2 players:

helo = {
[1] = {
	name = "helo1",
	active = false
},
[2] = {
	name = "helo2",
	active = false			
}
}

function DummyFunction()	
end

function PopulateRadioMenu(_id)
missionCommands.removeItemForGroup(_id.groupID, nil)
missionCommands.addCommandForGroup(_id.groupID, "GroupCommand1", nil, DummyFunction, _id)
missionCommands.addCommandForGroup(_id.groupID, "GroupCommand2", nil, DummyFunction, _id)

missionCommands.removeItem({"AllCommand"})
missionCommands.addCommand("AllCommand", nil, DummyFunction)

end

function CheckHeloActive()
for n = 1, #helo do
	if Unit.getByName(helo[n].name) ~= nil and helo[n].active == false then
		local _id = {
			name = helo[n].name,
			groupID = Unit.getByName(helo[n].name):getGroup():getID(),
			num = n
		}
		PopulateRadioMenu(_id)
		helo[n].active = true
	elseif Unit.getByName(helo[n].name) == nil then
		helo[n].active = false
	end
end
return timer.getTime() + 1
end
timer.scheduleFunction(CheckHeloActive, nil, 2)

Purpose of the test is to populate the F10 Radiomenu with two group specific commands and one general command.

Run the attached test mission as host to reproduce the bug:

1. Unpause the mission

2. Select helo1 and go into cockpit

3. Open F10 Radiomenu and observe the listed commands:

1. GroupCommand1

2. GroupCommand2

3. AllCommand

This is as expected

4. Hit escape, select helo2 and go into cockpit

5. Open F10 Radiomenu and observe the listed commands:

1. GroupCommand1

2. AllCommand

GroupCommand2 is not populated (or deleted instantly) even though it should display. If the above code is modified by removing the "AllCommands" related lines, GroupCommand1 and 2 behave as intended. As observed in further tests it seems that missionCommands.removeItem("some item") works fine the first time it is used but in subsequent uses not only removes "some item" but also the item directly above it.
