Code wont work again

So I am making a chunk claiming system, and while claiming land works, it only works for one player. Then other players cant claim land.

local CanShow = true
local ts = game:GetService("TweenService")

spawn(function()
	
	game.ReplicatedStorage.Events.ShowLandInfoUI.OnClientEvent:Connect(function(Owner, ChunkID)
		
		_ChunkID = ChunkID
		
		CanShow = true

		if Owner == "Unclaimed" then

			CanShow = true

		else

			CanShow = false

		end

		while game:GetService("RunService").Stepped:Wait() do

			if CanShow == true then
				
				ts:Create(
					script.Parent,
					TweenInfo.new(
						0.5,
						Enum.EasingStyle.Linear
					),
					{
						Transparency = 0
					}
				):Play()

			else

				ts:Create(
					script.Parent,
					TweenInfo.new(
						0.5,
						Enum.EasingStyle.Linear
					),
					{
						Transparency = 1
					}
				):Play()

			end

		end

	end)
	
end)

spawn(function()
	
	game.ReplicatedStorage.Events.HideLandInfoUI.OnClientEvent:Connect(function()

		CanShow = false
		ts:Create(
			script.Parent,
			TweenInfo.new(
				0.5,
				Enum.EasingStyle.Linear
			),
			{
				Transparency = 1
			}
		):Play()

	end)
	
end)

script.Parent.MouseButton1Click:Connect(function(Player)
	
	for i,v in pairs(workspace.Land_Chunks:GetDescendants()) do
		
		if v.ClassName == "StringValue" then
			
			if v.Value == _ChunkID then
				
				game.ReplicatedStorage.Events.ClaimLand:FireServer(game.Players.LocalPlayer.Name)
				
			end
			
		end
		
	end
	
end)

that is the code inside the button to claim land. It works for one player, but then it stops working. The chunk id is an ID thats passed over when a player walks into the zone

local ZoneM = require(game.ReplicatedStorage.Libraries.Zone)
local ReplicatedStorage = game:GetService("ReplicatedStorage")

local Container = script.Parent
local Zone = ZoneM.new(Container)

task.wait(0.5)

Zone.playerEntered:Connect(function(Player)
	
	ReplicatedStorage:WaitForChild("Events").ShowLandInfoUI:FireClient(Player, script.Parent.Owner.Value, script.Parent.ChunkID.Value)
	
end)

Zone.playerExited:Connect(function(Player)
	
	ReplicatedStorage:WaitForChild("Events").HideLandInfoUI:FireClient(Player)
	
end)

theres the code that fires the events and stuff to show stuff
