Account Stop Direct Debit wizard; may error with an unhandled exception

The Account Stop Direct Debit wizard may error with an unhandled exception for Revolving Credit Loans.

This occurs because the "Apply to minimum payments only?" option may not refresh the grid correctly. Clicking on the "Calendar" drilldown button, especially on the last row, may cause the error "An unhandled exception has occurred. Index was outside the bounds of the array.".
