Apparently it only happens when the SO in Quotation status is confirmed.  An SO that has 1 line item is confirmed and then when I go to Sales Orders I open that SO and it has 2 line items.  Its actually the same item but it is duplicated.  

THE DIFFERENCES

The first item has Ordered (3), Delivered (0), Invoiced (3) but the duplicated item has 0,3,0.  The other difference is the cost/price.  The first line item has the correct cost and price, in other words the cost value shows up in the cost column and the price value shows up in the price column.  But the second item has the cost value for both cost and price column.

Other than that the second line item totals zero and doesnt seem to be affecting the final invoice in which case its not affecting accounting.

I have images but apparently we cant upload images anymore.

We believe it may be related to anglo-saxon accounting which we recently activated but want to know why this happens and what for.
