tgb enemies issue

Im newbbie in this... but i start to make a battle space kind of game. i make a players spaceship, and an enemy spaceship. Both can shoot bullets and kill each other...
My problem becomes when i kill the enemy spaceship but this spaceship still shooting (even when i destroy it and after a new one spawns).
This happens when i set up its "take damage" behavior with more than one live.

I try to set the live in one... but then i cant make new enemy spaceships... if someone can help me. Thanks.
