2770050 - Purchase Order Is Going Into Approval Again After Adding An Item

You have approved a purchase order and after that you add another item to the purchase order.
You have scoped the approval process for purchase orders at item level and expect just the item to go for approval.
Instead of just the item going into approval, the whole purchase order is going into approval again on header level.
