How do I tween a sliding door (doors as models) without the orientation of the door changing?

Hi,

local tweenService = game:GetService("TweenService")
local info = TweenInfo.new()
local d1 =script.Parent.Parent:WaitForChild("d1")
local d2=script.Parent.Parent:WaitForChild("d2")
local info=TweenInfo.new(
	0.5,
	Enum.EasingStyle.Linear,
	Enum.EasingDirection.InOut,
	0,
	false,
	0
)


local CFrameValue1 = Instance.new("CFrameValue")
local CFrameValue2 = Instance.new("CFrameValue")
CFrameValue1.Value = d1:GetPrimaryPartCFrame()
CFrameValue2.Value = d2:GetPrimaryPartCFrame()


local d1open =  {Value = CFrame.new(-15.4, 4.5, -23.9)}

print(d1open)


CFrameValue1:GetPropertyChangedSignal("Value"):Connect(function()
	d1:SetPrimaryPartCFrame(CFrameValue1.Value)
end)
CFrameValue2:GetPropertyChangedSignal("Value"):Connect(function()
	d2:SetPrimaryPartCFrame(CFrameValue1.Value)
end)
local tween = tweenService:Create(CFrameValue1, info, d1open)
script.Parent.ClickDetector.MouseClick:Connect(function()
	tween:Play()

end)
	

--local tween = tweenService:Create(CFrameValue1, info, d1open)
--tween:Play()

tween.Completed:Connect(function()
	CFrameValue1:Destroy()
end)

(I'm only using one door at the moment until I can get it working properly) As you can see, the doors orientation rotates to (0,0,0) whereas I do want this to happen, only for the door to slide to the position I've given it. Any idea how I can fix this? Thanks.
