Event Receiver Spawn Error

Hi, I’m having a problem which is when i create a frame thrower effects in cascade and create an Event Generator in Collision, everything looks fine in the cascade viewport, but after i import into the level and hit play, the frame thrower starting point starting emit fire which not suppose to be there, just can’t figure out how to fix this problem

Simon
