How do I fix this sprite spawn

I have it to when a bullet collides with sprite, the sprite spawns another sprite...

i have a log that spawns a beaver when the player collides with a invisible block....when the player destroys the beaver , its suppose to spawn a light that shines up...well that all works accept when i duplicate the log and destroy the first beaver it spawns both lights, from log 1 and the copied one....

looks like this fixed it...not sure why though...I messed with the picking
