Expense auditor is unable to edit expense report distribution

Hi,

We were having an invoice (Expense claim) which was stuck in accounting due to multiple balancing companies in the expense lines. Claim was paid and imported into payables. Hence decided to cancel the invoice so that the Expense Auditor can edit the distribution and push it to Payables again. We cancelled the invoice, but now the expense auditor is unable to edit claim distribution. Can anyone please help us to resolve this.
