Why wont my tweening airport card gate work?

Here's the code. The door just bounces up and down they stops mid air! So weird. (the gui works fine) https://www.screencast.com/t/7xcx8WCil < explorer screenshot

local tweenService = game:GetService("TweenService")

local door1 = script.Parent.Parent.Door1
local door2 = script.Parent.Parent.Door2
local walkforwardgui = script.Parent.Parent.HitDetector.WalkforwardGUI

local cyl1 = script.Parent.Parent.Cylinder1
local cyl2 = script.Parent.Parent.Cylinder2

script.Parent.Touched:Connect(function(hit)
    if hit.Parent.Name == "Eco" or hit.Parent.Name == "FC" or hit.Parent.Name == "Premium" then
		local player = game.Players:GetPlayerFromCharacter(hit.Parent.Parent)
        local walkforwardguiclone = walkforwardgui:Clone()
        walkforwardgui.Parent = player.PlayerGui
        walkforwardgui.Main.Visible = true
        walkforwardgui.Main.Text.Text = "Walk forward, "..player.Name
		
		local properties =
		{
			CFrame = CFrame.new(cyl1.Position),
			Rotation = Vector3.new(0, 90, 0)
		}
		
		local tweenInfo = TweenInfo.new(1, Enum.EasingStyle.Bounce, Enum.EasingDirection.Out,
			1, true, 0
		)
		
		local tween = tweenService:Create(door1, tweenInfo, properties)
		tween:Play()
		
        wait(3)
		walkforwardgui.Main.Visible = false
    end
