I’m making it so when you press a button it changes your character but when i change back to my original it moves the original to where i moved my previous character

game.ReplicatedStorage.SetCharacter.OnServerEvent:Connect(function(plr, name)
	local oldModel = plr.Character
	local newModel = game.ReplicatedStorage.Characters[name]:Clone()
	local oldCFrame = oldModel:GetPrimaryPartCFrame()	
	newModel.Name = plr.Name
	plr.Character = newModel
	
	
	newModel.Parent = workspace
	newModel:SetPrimaryPartCFrame(oldCFrame)
	if not oldModel:FindFirstChild("NotActual") then
		oldModel.Parent = game.ReplicatedStorage.PlayerModels
	else
		oldModel:Destroy()
	end
end)

game.ReplicatedStorage.ChangeBack.OnServerEvent:Connect(function(plr)
	local oldModel = plr.Character
	local newModel = game.ReplicatedStorage.PlayerModels[plr.Name]
	local oldCFrame = oldModel:GetPrimaryPartCFrame()	
	plr.Character = newModel


	newModel.Parent = workspace -- [1] this follows current character loading behavior
	local oldSpeed = newModel.Humanoid.WalkSpeed
	newModel.Humanoid.WalkSpeed = 0
	wait(1)
	newModel.Humanoid.WalkSpeed = oldSpeed
	oldModel:Destroy()
	newModel:SetPrimaryPartCFrame(oldCFrame)
end)

Any help would be appreciated.
