Requisition raised by amount not showing quantity

Summary:

When we raise a requisition by Goods/Services billed by amount, I'm entering an amount of say 5, when you review the cart you can see it is showing the amount of 5 but there is no QTY etc, I would expect this to be 1. This is meaning that when we match an AP invoice to that order, despite not receipting it in, it shows as validated even though we have 3-way matching enabled. I assume as since there is no quantity it doesn't think to say it needs receipting.

I've attached some images from raising the req and the status of the invoice once matched (not receipted) and validated.
