couroutine loop works only once for a object the rest dont work?

local plr = game.Players.LocalPlayer

local PlayerGui = plr:WaitForChild('PlayerGui')

local ScreenGui = PlayerGui:WaitForChild('1stLoadingScreen')

local StartButton = ScreenGui.Frame.PlayLabel -- TextLabel

local rs = game:GetService("RunService")

local TS = game:GetService("TweenService")

  

  

MakeInvisible = coroutine.create(function(ObjectToMakeTransparent)

while true do

rs.RenderStepped:Wait()

ObjectToMakeTransparent.Transparency = ObjectToMakeTransparent.Transparency + 1

  

end

end)

  

while wait() do

StartButtonClone = StartButton:Clone()

coroutine.resume(MakeInvisible,StartButtonClone) -- Only runs for one clone the rest are all unaffected by this

game.Debris:AddItem(StartButtonClone,.2)

StartButtonClone.Parent = ScreenGui.Frame

StartButtonClone.Position = StartButton.Position

TS:Create(StartButtonClone, TweenInfo.new(.2, Enum.EasingStyle.Quad), {Size = UDim2.new(0.604, 0,0.150, 0)}):Play()

print(StartButtonClone.Position)

wait(1)

  

end
