Overdue bill reminders don't remain until paid

NormR

I have a set of monthly bills and transfers configured in the Bill Manager. The ones that are automatic enter themselves in the register and move on to display the next occurrence, as they should. For others that are configured for Quick Pay or Check Pay (and are _not_ set to auto-enter themselves in the register), I have set the recurrence date a little early, to provide a bit of cushion. When the due date has passed, they may display an 'Overdue' notice for a day or two but then cycle themselves to the next month, even if no payment action has been taken. This, of course, takes away the all-important reminder to pay the bill.

Any idea why this happens and how to prevent it? When I notice, I have to keep editing the schedule for all occurrences and rolling it back a month.
