Apps10 UPD15

I have an As-Built structure for a multi-level lot/batch tracked (non-serial) part PZ-000 lot/batch UDF-6, quantity of 1, that looks like this.

I released a multi-level repair shop order for PZ-000, lot size = 1. I manually issued lot/batch UDF-6 to the order. The Multilevel Repair Structure, though, shows lot/batch UDF-12 in the tree.

What could be the reason? Was this corrected in a later update?
