My script teleports the players a lot. Did I do something wrong?

To make it short, it often stutters. What I mean by that is that in the middle of the script there's a part where you teleport players. But it always teleports them twice.

Here's my script.

local textLabel = script.Parent

while wait(3) do
if game.Players.NumPlayers > 1 then
	wait(4)
	
	game.Workspace.Intermission.Playing = true
	for i = 15, 1, -1 do
		textLabel.Text = "Intermission:  "..i
		wait(1)
	end
	textLabel.Text = "Intermission:  0"
	wait(1)
	textLabel.Text = "I see you're looking at this text ;)"
	wait()
	textLabel.Text = " "
	wait(1)
	textLabel.Text = "pls w8 we make map ;,,("
	wait(2)
	local mapOne = game:GetService("ReplicatedStorage")
	mapcloned = mapOne.Map:Clone()
	mapcloned.Parent = game.Workspace
	local BarrierOne = game:GetService("ReplicatedStorage")
	barrierClone = BarrierOne.Barrier:Clone()
	barrierClone.Parent = game.Workspace
	
	textLabel.Text = "Making map,please wait..."
	
	wait(2)
	target = CFrame.new(2, 318.5, -3.5) 
			for i, player in pairs(game.Players:GetChildren()) do
   				if player.Character:FindFirstChild("HumanoidRootPart") then
				wait()
        	player.Character.HumanoidRootPart.CFrame = target + Vector3.new(0, i * 5, 0)
			wait()
		end
	end

	for i = 10, 1, -1 do
		textLabel.Text = "get ready b because it starts in: "..i
		wait(1)
	end
	workspace.Barrier:Destroy()
	
	for i,v in pairs(game.Players:GetPlayers()) do
		
		if v then
			
			wait()
			table.insert(_G.playersLeft, v.Name)
		end
		
	end
	wait(1)
	textLabel.Text = "Good luck!"

	wait()
	textLabel.Text = ""
wait(1)
for i = 60,2,-1 do

	textLabel.Text = i.." seconds left."
	wait(1)
	if i == 3 then
		textLabel.Text = "2 seconds left."
		wait(1)
		textLabel.Text = "1 second left!"
	end
end


textLabel.Text = "Clearing map..."

wait(2)

workspace.Map:Destroy()

wait(3)

textLabel.Text = "All good to go now! Let's get back to the intermission!"

else
wait(5)

	textLabel.Text = "You need 1 more player"
end
end
