We have issued a new release 22.214.171.124 (28 June 2008). When you amend or delete an existing scheduled item that has been added to your account transaction. We now handle this differently, by amending / deleting the scheduled item the relationship between the scheduled item and the instance of the transaction is broken, and the existing transactions is changed to a normal account transaction. A new scheduled account transaction is then created. Any additional transactions can then be deleted manually.
