"Abandon Transaction" doesn't work

A couple of days ago i received some sats that never were confirmed, the tx is not in my mempool, looked for it in several block explorers and is not there neither, i click on "Abandon Transaction" on Specter but is still showing that unconfirmed transaction and doesn't delete it from History.

Specter v1.7.1

Start by reproducing the issue in Specter v1.7.1 with an unconfirmed transaction that is no longer in the mempool or block explorers. Trace the “Abandon Transaction” action and transaction history behavior; done means the abandoned transaction no longer appears in History.
