Tweening the orientation of a part is also changing the position?

I have this model of a door, and when I test it straight out of workspace, it works fine, however when I pull it out of ServerStorage and then test it, the model rotates and changes its position to an area across the map. Anyone see anything in my code that might be causing this?

local TweenService = game:GetService("TweenService")
local door = script.Parent
local doorRoot = door.PrimaryPart
local proxPrompt1 = door:WaitForChild("Prox1"):FindFirstChild("ProximityPrompt")
local proxPrompt2 = door:WaitForChild("Prox2"):FindFirstChild("ProximityPrompt")


local doorSwingInfo = TweenInfo.new()

local doorOpenTween = TweenService:Create(doorRoot, doorSwingInfo, {
    CFrame = doorRoot.CFrame * CFrame.Angles(0, math.rad(90), 0)})

local doorCloseTween = TweenService:Create(doorRoot, doorSwingInfo, {
    CFrame = doorRoot.CFrame * CFrame.Angles(0, math.rad(0), 0)})
