Resetting Checking Account Caused Huge Difference Between Online Balance and Ending Balance

Question

Had to reset my checking account because my bank has us change passwords every-now-and-then. I had to reset because I went into Password Vault to change my password but it wasn't required?
 I reset my account and linking it to my existing.
 But, now Quicken shows that I ending balance is -$800 and the online balance is $300.
 I over drew by $800.00???

Any idea why this happened???

I had encountered a problem where resetting the account would cause the very first transaction from years ago to be duplicated.

You may be experiencing a similar problem. Check your opening balance.
