"scout" Tower still thinks dead zombie is alive tower defense?

Help and Feedback Scripting Support

in the last post i used some advice to make a tower for my tower defense game that will shoot 0.5 speed, 2 damage zombies have 4 health

but in the output, when the zombie is dead, my code thinks it is still alive, and tries to shoot at it for a while, so it lets the zombies walk without dying, then it just selects another random zombie, but it is supposed to choose the second zombie, and after that it is just too late.

code:

local parent = script.Parent

local Zone = require(game.ServerScriptService.Zone)
local zone = Zone.new(parent)
local enemies = {}
local target = nil

while wait(0.5) do
	zone.partEntered:Connect(function(x)
		if table.find(enemies, x) == nil then
			table.insert(enemies, x.Parent)
		end
		
		if x.Parent:FindFirstChild("Config") then
			if target == nil then
				target = enemies[1]
			end
		end
	end)
	zone.partExited:Connect(function(x)
		table.remove(enemies, 1)
		target = nil
		pcall(function()
			target = enemies[1]
		end)
	end)
	print(target, enemies)
	if target ~= nil then
		local success, err = pcall(function()
			target.Config.Health.Value -= 2
		end)
		if err then
			target = nil
		end
	else
		pcall(function()
			if zone:getParts()[1].Parent:FindFirstChild("Config") then
				target = enemies[1]
			end
		end)
	end
end

btw i used zone region3
