Help with multiple custom (active) abilities in the same unit.

[KaiserG]

Well, I basically need to use 4 modified "Goblin Land Mine" abilities in the same unit. But when i test the skills ingame, they all 4 trigger at the same time, casting only the first of the 4. This always happens to me when i use the same base ability for different custom abilities. Is there any way to make them work like separate abilities without triggering them all at the same time?
