Quest Icon - Minimap

[urachi]

I created three Green Quest Icons on the minimap. But i only find "Destroy last created Minimap Icon" as a trigger to remove the created quest icons when the quest is done. It destroy the last one and no more previous ones. Any idea on it? Variables i guess?

It are the new Mini Map icons. For example, the one they used for the Culling of Stratholme to track Malganis. Its the Boss icon. I just can't find a way to remove them from the minimap again since the only trigger i see is "Destroy last created" and that's not enough, i can't even apply a variable to it.
Anyone already experience on those new Minimap Icons?
