:Clone() only works one time, not the second time. Please can someone help? [SOLVED]

So I am making a final boss battle with waves of robots attacking the player. Once all robots are dead, they have access to two buttons. They must press these two buttons within 15 seconds otherwise the wave will be repeated. To do this, I simply clone the same folder from serverstorage back into the workspace again. However, this doesn't work. Please help!

local debounce = false

local leftbutton = game.Workspace.FinalRoom.ButtonL
local leftlightning = game.Workspace.FinalRoom.LightningL
local rightbutton = game.Workspace.FinalRoom.ButtonR
local rightlightning = game.Workspace.FinalRoom.LightningR

local robotboss1 = game.ServerStorage.RobotBoss1:Clone()
local robot1reattempt = game.ServerStorage.RobotBoss1Attempt2:Clone()
local robotboss2 = game.ServerStorage.RobotBoss2:Clone()
local robotboss3 = game.ServerStorage.RobotBoss3:Clone()
local robotarmy = game.ServerStorage.RobotArmy:Clone()
local fakerobots = game.ServerStorage.FakeRobots:Clone()

game.ServerScriptService.Round1Handler.Disabled = false
game.Workspace.FinalRoom.Barrier:Destroy()

function startround1()
	if debounce == false then
		debounce = true
		game.Workspace.CurrentRound.Value = 1
		game.ServerStorage.FinalRoomBarrier.Parent = game.Workspace
		game.Workspace.DiedBefore.Value = true
		game.Workspace.FinalBossMusic:Play()
		game.Workspace.FinalRoom.Vincent.Animate.Disabled = false
		wait(3)
		game.Workspace.Teleporter:Play()
		robotboss1.Parent = game.Workspace
	end
end

function startround2()
	if script.Round1Deaths.Value == 2 then
		--Open the buttons!
		leftbutton.Head.ProximityPromptL.Enabled = true
		rightbutton.Head.ProximityPromptR.Enabled = true
		leftlightning.LightningLL.Parent = game.ServerStorage
		leftlightning.ButtonBarrier.CanCollide = false
		rightlightning.LightningRR.Parent = game.ServerStorage
		rightlightning.ButtonBarrier.CanCollide = false
		wait(15)
		if game.Workspace.CurrentRound.Left.Value == true and game.Workspace.CurrentRound.Right.Value == true then
			wait(2)
			game.Workspace.CurrentRound.Value = 2
			game.Workspace.CurrentRound.Left.Value = false
			game.Workspace.CurrentRound.Right.Value = false
			game.ServerScriptService.Round2Handler.Disabled = false
			game.Workspace.FinalRoom.Light1.Light.LightPart.Beam.Attachment1 = game.Workspace.FinalRoom.Light1.Light.LightPart.End2
			game.Workspace.TurningLights:Play()
			wait(3)
			--RESET BUTTONS
			leftbutton.Head.ProximityPromptL.Enabled = false
			rightbutton.Head.ProximityPromptR.Enabled = false
			game.ServerStorage:WaitForChild("LightningLL").Parent = leftlightning
			leftlightning.ButtonBarrier.CanCollide = true
			game.ServerStorage:WaitForChild("LightningRR").Parent = rightlightning
			rightlightning.ButtonBarrier.CanCollide = true
			--
			game.Workspace.Teleporter:Play()
			robotboss2.Parent = game.Workspace
		else
		--Too late! Restart the round
		leftbutton.Head.ProximityPromptL.Enabled = false
		rightbutton.Head.ProximityPromptR.Enabled = false
		game.ServerStorage:WaitForChild("LightningLL").Parent = leftlightning
		leftlightning.ButtonBarrier.CanCollide = true
		game.ServerStorage:WaitForChild("LightningRR").Parent = rightlightning
		rightlightning.ButtonBarrier.CanCollide = true
		script.Round1Deaths.Value = 0
		wait(1)
		game.Workspace.Teleporter:Play()
			robotboss1.Parent = game.Workspace
		end
	end
end

This is a sample of one of the functions. robot1reattempt is the backup option because it is the same as robotboss1 but a different folder which works. However, this is not good enough as this breaks when it tries to clone again as well.
