Did you have something you might have reversed or fixed for the previous month after you reconciled it? If so it is going to show in your new month a debit and a credit. 

Discovered the issue ; had to do with Sage 50 update. But all is well now. Thanks for your help

Anytime.  I just think of things that go wrong for me to see if it will help someone else.  Glad you found the error.
