When I try to install this perk pack the perks don't show up as the perks and they do not work properly an example is phd flopper shows up as a differently textured jug can anyone tell me how to fix this?

So I created a second zone in my map and when I open the door leading to the map it says the zone is activated, but the zombies are not spawning - the zombies are only coming from the first zone - and idk why this is happening.
