Hi, 
 
I have imported the bank feeds and there are old transactions since 2015, 2016, 2017 which were imported this time. I have used the bank feed and the data import before, but never had this issue. 
i am using QuickBooks Enterprise, and would need your guidance if you know how can I delete these old transactions imported, without redoing all the bank reconciliations for 6 years...
 
Thank you!
