I went in to the bank feed to today to see what needs to be updated still. I was surprised to see a transaction from September because I thought I had already reconciled this month. The transaction is our online credit card payment. I am not sure if it is because it is reconciled but it won't match with the check ACH I created. The intial date was off a day but I changed it and it still isn't matching. 

Since I know I have already accounted for this payment in our books, and they have been reconciled for the month, can I just delete it somehow or should I worry about matching it?

I have attached an image showing the transaction in the news feed with the ACH check I wrote. But I don't know why they won't match.
