Deleting unwanted /wrong transactions from reconciliation window...

SUGGESTED

New user here.  Picking up from someone who has doubleposted a number of transactions, either through General Ledger Screen or Purchase Windows.  These all show up as  outstanding transactions in the reconciliation window. 

If I go back and delete the journal entry, the posting stays in the rec window.  I have 30 outstanding rec transactions that really need to be deleted.  Clicking on deleted transactions shows a "There is no data to report" - so it seems to be gone in the GL.  How do I clean up my rec window from these unwanted outstanding transactions?  Thx Bryan
