It appears something has affected the ruleset we had to copy PO Numbers from SO up to EL. Because now it appears the PO Number is also being copied from EL down to the Shipment. As a result when we have a load with two SO's with different PO numbers, each shipment is bearing the PO Number for the same shipment as well as other shipment under that EL.
This is confusing to users, but completely messes with the integration we have built between TMS and Samsara.
On both Prod and QA there are numerous examples of this bug. for example LD121901 in Production had two shipments and both of those shipments have two PO numbers, one valid to that shipment and one not.

Geno applied fix in QA and after we verified, applied the same to Prod.
