The "alert" sounds come from other mobs that shouldn't have your AI.
I've set it so that the only tickable_entities is Zombie and ZombieVillager. But still I have the sounds coming from creepers, spiders and skeletons. 👎
It sort of breaks the immersion, so I'd love a fix for this 👎

Can't reproduce, config is working perfect for me, tested with creeper targetting me, only made sound when I had "Creeper=true". Make sure to close the game when making changes in that config file.
