Part not deleting if there are duplicates of its self?

So I have a box system and when the player touches the box I want the box to destroy. It works fine if there is one box in workspace but if there is two the boxes do not delete.

m = require(game:GetService("ServerScriptService").MainModule)
spawnArea = game.Workspace:WaitForChild("BoxSpawnArea")

function newNormalBox(cash)
	box = game:GetService("ReplicatedStorage"):WaitForChild("Boxes"):FindFirstChild("NormalBox"):Clone()
	box.Parent = game.Workspace
	box.Position = Vector3.new(math.random(-spawnArea.Size.x/2,spawnArea.Size.x/2),125,math.random(-spawnArea.Size.z/2,spawnArea.Size.z/2))
	
	local AlreadyHit = false
	local function touch(hit)
		local hum = hit.Parent:FindFirstChild("Humanoid")
		if hum~=nil and AlreadyHit ~= true then
			game.Workspace.SoundsEffect.BoxHit:Play()
			AlreadyHit = true
			game.Players[m.PlayerName].leaderstats.Cash.Value = game.Players[m.PlayerName].leaderstats.Cash.Value + cash
			box:Destroy()
		end
	end
	box.Touched:Connect(touch)
end

function newGemBox(gems)
	box = game:GetService("ReplicatedStorage"):WaitForChild("Boxes"):FindFirstChild("GemBox"):Clone()
	box.Parent = game.Workspace
	box.Position = Vector3.new(math.random(-spawnArea.Size.x/2,spawnArea.Size.x/2),125,math.random(-spawnArea.Size.z/2,spawnArea.Size.z/2))
	
	local AlreadyHit = false
	local function touch(hit)
		local hum = hit.Parent:FindFirstChild("Humanoid")
		if hum~=nil and AlreadyHit ~= true then
			game.Workspace.SoundsEffect.BoxHit:Play()
			AlreadyHit = true
			m.Gems = m.Gems + gems
			box:Destroy()
		end
	end
	box.Touched:Connect(touch)
end

function newGoldBox(cash,gems)
	box = game:GetService("ReplicatedStorage"):WaitForChild("Boxes"):FindFirstChild("GoldBox"):Clone()
	box.Parent = game.Workspace
	box.Position = Vector3.new(math.random(-spawnArea.Size.x/2,spawnArea.Size.x/2),125,math.random(-spawnArea.Size.z/2,spawnArea.Size.z/2))
	
	local AlreadyHit = false
	local function touch(hit)
		local hum = hit.Parent:FindFirstChild("Humanoid")
		if hum~=nil and AlreadyHit ~= true then
			game.Workspace.SoundsEffect.BoxHit:Play()
			AlreadyHit = true
			game.Players[m.PlayerName].leaderstats.Cash.Value = game.Players[m.PlayerName].leaderstats.Cash.Value + cash
			m.Gems = m.Gems + gems
			box:Destroy()
		end
	end
	box.Touched:Connect(touch)
end

function newDiamondBox(cash,gems)
	box = game:GetService("ReplicatedStorage"):WaitForChild("Boxes"):FindFirstChild("DiamondBox"):Clone()
	box.Parent = game.Workspace
	box.Position = Vector3.new(math.random(-spawnArea.Size.x/2,spawnArea.Size.x/2),125,math.random(-spawnArea.Size.z/2,spawnArea.Size.z/2))
	
	local AlreadyHit = false
	local function touch(hit)
		local hum = hit.Parent:FindFirstChild("Humanoid")
		if hum~=nil and AlreadyHit ~= true then
			game.Workspace.SoundsEffect.BoxHit:Play()
			AlreadyHit = true
			game.Players[m.PlayerName].leaderstats.Cash.Value = game.Players[m.PlayerName].leaderstats.Cash.Value + cash
			m.Gems = m.Gems + gems
			box:Destroy()
		end
	end
	box.Touched:Connect(touch)
end

chance = {1,1,1,1,1,1,1,1,1,2,2,2,2,2,2,3,3,3,4}

while wait(.10) do
	a = chance[math.random(1,#chance)]
	warn(a)
	if a == 1 then
		newNormalBox(math.random(50,500))
	else if a == 2 then
		newGemBox(math.random(1,3))
	else if a == 3 then
		newGoldBox(math.random(2000,4000),math.random(1,10))
	else if a == 4 then
		newDiamondBox(math.random(20000,50000),math.random(5,40))
	end
	end
	end
	end
	game.StarterGui:SetCore("SendNotification",{
		Title = "NOTICE"; 
		Text = "A box has spawned somewhere in the map. You should go see what's inside!";
