Guard Spawner Device Not Shooting When Using MaintainFocus

[Soy_Ema_31 (Soy_Ema_3)]

I watched a tutorial where the guard only used MaintainFocus, and it would look at the player and shoot. But in my case, the guard only looks at me but does not shoot.

Simple Code:

GuardSpawner.AlertedEvent.Subscribe(OnAlerted)

    OnAlerted(Result:device_ai_interaction_result):void=
        if:
            Guard:=Result.Source?
            Target:=Result.Target?
            Character:=Guard.GetFortCharacter[]
            Focus:=Character.GetFocusInterface[]
        then:
            spawn{Focus.MaintainFocus(Target)}
