Unable to create Invoice for 4 way matched PO on Supplier Portal

Summary:

We have created 4 way matched Purchase Orders (both expense and Inventory), with match against receipt and Inspection required. Even though we are completing all the steps, when a supplier user tries to create an Invoice from Supplier portal, there are no lines available for the user to match.

Supplier user is able to match 2-way and 3-way POs

We are also unable to receive this PO in self service receiving even though it has a requester.
