If I schedule an eBill series with a $0.00 amount, the eBill is duplicated in the Bills & Income list, but not in the transaction register. If I change the scheduled amount to $0.01, it is not duplicated in either location. There must be a bug in the software that duplicates the $0.00 eBill entry in Bills & Income. (I use the $0.00 amount as a reminder of a potential bill looking ahead in a transaction register.)
