Profit and loss Statement Inventory cost changed after update

Perfect thank you… Now understood…

So the issue is now clear, it appears there has been a change to how manager handles selling inventory at 0 cost and how that reports on the P&L See attached images, the one from the old version shows very few transactions, in fact only the transactions that have been the item invoiced at cost. wheras the current version shows all items billed at 0 cost or otherwise…

The back and forward consequences of this are not very fun!
