Hi there, @Edward13.
I'll share some information on why QuickBooks downloading duplicate transactions from the bank feeds.
QuickBooks automatically downloads the maximum number of transactions available from your bank once it is connected to online banking. Also, each bank account is linked differently to the program, and sometimes there are cross wires. That said, QuickBooks might download duplicate transactions occasionally.
Removing the duplicates from the bank feeds is the best way to fix the issue. I understand you have to review each of the transactions to make sure you're not removing the already matched one.
I'll be adding this article for more guidance: Remove duplicate transactions in QuickBooks Desktop.
However, if you still encounter the same issue, I recommend reaching out to our QuickBooks Support Team. This way, they can further check on this matter and provide some troubleshooting steps to get this resolved.
Come back to this post and let me know how it goes, @Edward13. I want to make sure you're taken care of.
In case you need help with reconciling your account, you can scan through this article for your reference: Reconcile an account in QuickBooks Desktop.
Have a good one!
