Can't delete an imported bank statement causing duplicate transactions

Question

Before I set up a bank feed, I used to manually import QIF files from my bank. The second time I did this, it created 2 duplicate transactions that I am struggling to delete.

I tried to delete the offending QIF file but received an error saying:

"You cannot undo the approval because the transaction has been reconciled"

Update: even though it said the QIF file could not be deleted, it did it anyway and was gone when I logged back in again. So this is resolved.
