Hello, Fampack. 

Right now, we haven't received similar issues reported with Bank of America about refreshing the accounts, and all say 3 or 4 days ago. 

To get this sorted out, I'd suggest getting in touch with our Customer support team to have this investigated. 

1. In your QuickBooks Desktop program, go to Help > QuickBooks Desktop Help.
2. In the Have a Question window, click the Contact Us link at the bottom.
3. From the Contact Us page, select any topics.
4. Under Here's how to connect with a QuickBooks expert section, click the Start a Message or Get Phone Number button.

You can also get our direct phone number on this link: Contact QuickBooks Desktop support.  

Also, about duplicate transactions in the Bank Feeds, we can delete it. But before doing so, please know that deleting transactions depends on the mode you're using. You can check out this link to learn more about switching between bank modes.

For the Side-by-Side mode, here's how:

1. Go to the Banking > Bank Feeds > Bank Feeds Center.
2. In the Items Reviewed section, choose the account with the transactions you want to remove.
3. Click Items to Delete.
4. Select the transactions you want to delete.
5. Hit Delete Selected. Then select Yes to confirm. Tip: If you're already matched your statement, you can select Select all downloaded transactions older than and set the date to the last statement end date. Then select Delete Selected. You may need to switch to Register mode to delete everything.

For reference, you can read this article: Remove duplicate transactions in QuickBooks Desktop.
