Are you trying to permanently delete or remove transactions that you have already "deleted" in EveryDollar?
Once you delete a transaction in EveryDollar it can still be viewed and also restored to it's previous location from the "Deleted" transactions queue.
Once a transaction has been deleted and is in the "Deleted" transactions queue you can click the small restore arrow (shown in the image below) to restore it back to the budget item it was assigned to previously (or the "New" transactions queue if it was not assigned to a budget item previously).
There is not a way for you to permanently delete a transaction(s) that have been deleted and are in the "Deleted" transactions queue, but after several months transactions will no longer be visible from showing in the "Deleted" transactions queue.
