Self service Browser - Back Button

We use Procurment Card functionality in Payables.

When a user is in the Verify Procurement Transaction screen (browser form) and selects the Validated link to Verify a transaction, the user sometimes uses the back button to check the merchant name before completing the description and changing the accounts codes.

After using the back arrow button and selecting Validated again, an error message appears but after some Cancelling and movement is able to get back to complete theprocessing.

However, sporadically, the GL account codes disappear from the record (on the screen and in the table) and the user can no longer get into the record to complete the transaction.
