P40072 not allocating preferred branch plant for EDI orders.

Good Afternoon.

We are running across a very strange issue;

We recently upgraded from E1 812 to E1920 and when getting sales orders from  EDI, there is one particular item that is not being assigned to the correct branch plant as set up in P40072

The issue is only happening with one item and in E1920, all order items are working as expected.

Any advise will be greatly appreciate it.

Thanks.
