Potentially incorrect number of units/price display in order cost details

Overview: The number of units showing in the summary area of the PO does not match the number in the POLs. I have a PO with aprox. "totalItems": 901 but in the TotalUnits fields only 500 units show for PO

Steps to reproduce:

1. Log in to FOLIO Snapshot as diku_admin
2. Go to the orders app
3. Create a PO, then create 900 PO lines with some number of units
4. Change the PO from pending to open
5. View the Total Units in the PO Summary section

Expected result: the number of units should match the total quantity across all PO lines

Actual result: It doesn't
