When the doors of my sliding door opens, the orientation changes?

Ok so basically, I scripted a sliding door, and the problem is that I can't get the doors to stay at a constant orientation. The doors open fine and everything except for one thing. When the doors open, they turn sideways and don't face the right way. Here is all of my code I did. I used tweening.

local TweenService = game:GetService("TweenService")
local door1 = script.Parent:WaitForChild("Door1")
local door2 = script.Parent:WaitForChild("Door2")
local tweeningInformation = TweenInfo.new(
    0.5,
    Enum.EasingStyle.Linear,
    Enum.EasingDirection.Out,
    0,
    false,
    0
)
local door1Open = {CFrame = CFrame.new(6, 18, -157)}
local door2Open = {CFrame = CFrame.new(-81, 17.5, -156.5)}
local door1Close = {CFrame = CFrame.new(-23, 18, -157)}
local door2Close = {CFrame = CFrame.new(-54, 17.5, -156.5)}
local tween1open = TweenService:Create(door1,tweeningInformation,door1Open)
local tween1close = TweenService:Create(door1,tweeningInformation,door1Close)
local tween2open = TweenService:Create(door2,tweeningInformation,door2Open)
local tween2close = TweenService:Create(door2,tweeningInformation,door2Close)

script.Parent.Detector1.Touched:Connect(function(hit)
    tween1open:Play()
    tween2open:Play()
    wait(2)
    tween1close:Play()
    tween2close:Play()
end)
script.Parent.Detector2.Touched:Connect(function(hit)
    tween1open:Play()
    tween2open:Play()
    wait(2)
    tween1close:Play()
    tween2close:Play()
end)
