[SOLVED] 2 different instances of pre-shipped behavior?

Hey guys,
I've created an actor (Player), attached "fire a bullet" (from library) behavior to him, then I've created another actor (Enemy) and attached another "fire bullet" (from library) behavior to him as well.
Now I want to tweak those behaviors, but it comes out that this is one same behavior. And whatever I change for the Player, applies to the Enemy.
Is there a way to create different instances of pre-shipped behaviors, when created from library?
Thanks.

You can right click the behavior and copy it, then modify the copy.

Thank you.
I have duplicated it from Dashboard (Under Logic section)
