Asset Management Transaction Reversal blank Reversal Accounting Date for Asset Additions

We upgraded to FSCM 9.2 a few months ago. PUM 26, Tools 8.55. Our finance team is interested in using the AM transaction reversal functionality, but encountered an issue in testing. Reversal worked for all transaction types, except reversing Asset Addition, even when the criteria outlined in PeopleBooks is met. Depreciation has been run, and accounting entries are not yet posted to the GL.

PeopleBooks states that the Reversal Accounting Date is initially the system date, but can be changed. In this case, that field is blank, and disabled. This actually matches the PeopleBooks screenshot of the Transaction Reversal Page, and demo system with PUM 27. The field description for Reversal Accounting Date is not reflected in the screen shot used, and I'm trying to determine why and how to fix it.
