Quicken Starter Edition 2011

This forum really isn't for Quicken.

Is it possible your register was re-sorted in other than date sort order? In QuickBooks, you can see the sort order at the bottom of the register on the left side. Not sure for Quicken.

I see you want to resolve unmatched balances in your account, @RDR5. 

Do you presently use Quicken?  If so, I advise reaching out to them. They're able to investigate the cause of the issue and offer you the most effective fix.

On the other hand, if you use QuickBooks Desktop, I suggest looking through your bank statement and comparing it with QuickBooks. Then, you can manually upload the missing transactions. See this guide for the detailed steps: Download bank feed transactions in QuickBooks Desktop.

If everything is good, you can also check this article about reviewing and matching transactions: Add and match Bank Feed transactions in QuickBooks Desktop.
