It seems that the previous version 3.87 has no such issue. How could I reverse back to version 3.87? Thank you.

Hi all, I experience a major problem in latest version express invoice plus. v3.90. When I create a sale order, the item quantity is deducted in the item list accordingly, but when I convert this sales order to an invoice, the item quantity is deducted in the item list again. Anyone has the same problem? Thank you.
