Dragging UI issues, what am I doing wrong?

For some reason, this does not work…I print the position of it and it says it updates but the actual UI does not actually move. The Item is a button, and inside the button is a few extra components. Another thing to note is that it is inside of a UI Grid layout. Here is code:

function Utility.DragItem(Item, ConnectionManager)
	print(Item)
	local InitialPos = Item.Position
	if not Dragging then
		Dragging = true

		print("Drag")

		local ConnectRunService = RunService.Heartbeat:Connect(function(deltaTime)

			local MousePos = UserInputService:GetMouseLocation()
		
			Item.Position = UDim2.new(0,MousePos.X,0,MousePos.Y)

			print(Item.Position)

		end)

		ConnectionManager:AddConnection("ItemDragConnection", ConnectRunService)

	else

		print("StopDrag")

		Dragging = false
		Item.Position = UDim2.new(InitialPos)
		ConnectionManager:Remove("ItemDragConnection")

	end
end
