My tower keeps targetting the wrong zombie and getting the wrong values, how do I fix it?

I am working on a tower defense styled game and so I made a tower script that gets the zombies within range of the tower and then does a "for i" loop to get which one is the furthest, but when I run the script it keeps targetting the wrong zombies, I tried several things to fix it but to no avail and I need some support.

Script: (Serverside)

--//Services
local players = game:GetService("Players")
local repStorage = game:GetService("ReplicatedStorage")

--//Variables
local tower = script.Parent
local towerHumanoidRootPart = tower:WaitForChild("HumanoidRootPart")
local towerAnimations = tower:WaitForChild("TowerAnimations")
local towerSoundEffects = tower:WaitForChild("TowerSoundEffects")
local towerStats = tower:WaitForChild("TowerStats")

local pathsFolder = workspace:WaitForChild("PathsFolder")

local function shoot()
    while wait(.01) do
        for i, v in pairs(pathsFolder:GetChildren()) do
            local zombiesFolder = v:WaitForChild("Zombies")

            for i, z in pairs(zombiesFolder:GetChildren()) do
                local zombieHumanoidRootPart = z:WaitForChild("HumanoidRootPart")

                if (zombieHumanoidRootPart.CFrame.p - towerHumanoidRootPart.CFrame.p).magnitude <= require(towerStats).Range then
                    local zombiesDistanceWalkedValues = {}

                    local zombieStats = z:WaitForChild("ZombieStats")
                    local zombieDistanceWalked = zombieStats:WaitForChild("DistanceWalked")

                    table.insert(zombiesDistanceWalkedValues, zombieDistanceWalked.Value)

                    local furthestDistance = 0

                    for i, d in pairs(zombiesDistanceWalkedValues) do
                        if d > furthestDistance then
                            furthestDistance = d
                        end
                    end

                    if zombieDistanceWalked.Value == math.max(furthestDistance) then
                        towerHumanoidRootPart.CFrame = CFrame.new(towerHumanoidRootPart.CFrame.p, zombieHumanoidRootPart.CFrame.p)
                        towerHumanoidRootPart.Orientation = Vector3.new(0, towerHumanoidRootPart.Orientation.Y, 0)

                        wait(require(towerStats).FireRate - .01)
                    end
                end
            end
        end
    end
end
