Accounts; when Account Type "Allow Credit/ Zero balance before maturity date?" option is checked the final payment date may be confusing

Where an Account Type's "Allow Credit/ Zero balance before maturity date?" option is checked the final payment date may be confusing.

It may lead to the Financial page stating the Account will be paid off early, but has already been in credit for some time - as payments continue right through to the Maturity date.

The final payment date is now shown as the payment immediately after where the Account was last in debit (or at least greater than the residual value).
