Abandoning a transaction doesn’t delete it from the pockets. It solely lets the pockets know that it will possibly ignore the transaction when setting up new transactions. They continue to be within the pockets within the occasion that the transaction is rebroadcast (presumably by another person) and due to this fact has the potential of confirming. They’re in any other case okay to depart within the pockets and they are often ignored.
Transactions could be forcibly deleted from the pockets file by utilizing the removeprunedfunds RPC. Nevertheless, be very cautious with this as eradicating transactions which are nonetheless related can lead to the pockets misbehaving, equivalent to by accident double spending already spent outputs, or displaying and incorrect stability. Solely do that if you’re certain the transaction is irrelevant (i.e. all outputs already spent, transaction is conflicted, and many others.). It’s in any other case okay to depart irrelevant transactions within the pockets.
In your case, as a result of the transactions are marked as deserted, they don’t seem to be fully irrelevant. They’ll nonetheless be revived if somebody had been to broadcast them once more. As such, I’d advise leaving the transactions alone. You may take away them as soon as they turn into conflicted. For that to occur, one other transaction spending the identical inputs must turn into confirmed.
