3772730 - The Sold To Email field on an invoice reconciliation document is not editable

I notice that the Sold To Email field on an Invoice Reconciliation (IR) document is read-only and cannot be modified. The field displays the email address of a user who is no longer active in the organization, and I am unable to update it to a valid user.
