Hi @raf819
It looks like you've already had a reply to the question you posted yesterday:
How do I correct the statement ending date in the bank reconciliatio...
You should have gotten an email telling you there was a reply, but if not, just click on the above link to go back to your original post.
And to confirm the main question asked, did you actually ACCEPT the Reconciliation with the wrong date? I'm not sure how you had a $0 Balance, so I would hope you actually didn't Accept and Close that Reconciliation.
If you didn't when you go back it will show you where you left off, but you also have the option to go back and adjust the numbers. Just go back to that screen and correct the date.
