Duplicate transactions not deleted

My yr end 24 accounts are with the accountant. Because I had bank feeds running and so "auto reconcile", as well as manual entries, for same (a hang over from transferring from Reckon) then some entries were duplicated. My accountant says he Deleted these entries and GL reconciles with bank for Yr end (31 Mar 24). All "deleted" entries predate year end. However I have, subsequent to yr end, done 1 manual reconcile but before accountant started deleting duplicates. Now when I try to manually reconcile all the supposedly deleted entries still appear for ticking, along with entries subsequent to the last recon., which of course are to be ticked in, and I cannot reconcile with the Difference exactly equal to the total of those supposedly deleted entries. How do I get rid of these entries and the Difference they represent?
