We are working to fix a reconciliation issue caused by a deleted reconciled transaction and I would like to confirm the best approach. 

A payment from Feb was deleted yesterday because it was identified as a duplicate, this payment had already been reconciled. All months from Feb to July have been reconciled correctly, until that payment was deleted yesterday and now Feb shows a negative balance because of that deleted payment. I originally noticed because I was working on reconciling August, and despite every transaction matching the bank register, Augusts balance was showing a negative and not zeroing out. That is when I noticed Feb was messed up because of that duplicate payment that was deleted. 

However, in the bank register, In Feb I can see the payment (I assume the original payment and not the duplicate) and it shows an R as if its reconciled. But as mentioned, when I view the February report, it shows that payments balance as "-xyz". Its almost as if the duplicate and the original were both reconciled originally. 

I've done some research, and the best solution I have found is to undo the February reconciliation and redo it so that the chain is restored and not affecting ending and beginning balances of future months. However, I cant undo February without first undoing July, June, May, April and March in order. Before I go down that route, which I know is not preferred, is there a way to Fix February without having to undo it and all those other months? 

If you have questions about the situation, please ask and I will respond with an answer as soon as possible.
