OK, now to figure out how that can happen. The only way I can auto-reverse a retrieved batch is to: i) create a new GL batch, ii) use the Copy function to copy the retrieved transactions from the original batch to this new batch, iii) the new batch can be auto-reversed. However the clue that this has happened is that the new batch shows "Ledger" = "GL" (though the transactions keep "IC"). Can you confirm that the "Ledger" column shows "IC" and not "GL" when looking at the batch list? I know that's an unlikely occurrence but we need to rule it out.
