Empty Batch showing total transaction numbers and amount

Hi All

I am using GP2015.I have some Sales Transaction (not SOP Transactions) in Batch A. I moved these transaction into Batch B successfully from window. But batch A is still showing total transaction number and transaction amount even none of the invoice is assigned to Batch A. I have cleared all these batches by running reconcile. My question is why it is happening and it happened for 17 batches. Any idea or clue.
