I understand where you're coming from, @Kathy710.

When you change a transaction from the bank feeds, it usually has no impact on other transactions. I'd also suggest following the troubleshooting steps suggested by my colleague @Rubielyn_J from the previous post. 

If you still get to experience the same problem, kindly reach out to Customer Support. That way, they can look into it further and give you the finest answer to your issue.

I'm adding this helpful guide on how to manage transactions in QBO: Categorize and match online bank transactions in QuickBooks Online.
