How do I truly delete duplicate bank transactions?? If I delete a duplicate entry from register, it shows up in bank transactions and I'm caught in an endless loop.

This happened because I noticed a single missing trx so I uploaded bank QBO. When I've done this in the past, it only added missing trx. Today it added every single trx. They show up in my register as duplicates. If I delete a transaction from my register, it re-appears on the bank transactions for review. I don't see a way to permanently delete a transaction anymore.
