"Edit items" strange behavior (drop shipments items)

[biletnikov]

Hello all, we faced a strange situation in OFBiz 9.04. We created an order with two drop shipment items, each item belongs to different Supplier. After that, if we click "Edit items" in the "Actions" tab and change something or do not change, the sales tax (VAT) and shipment fee are duplicated for the last shipment group. To demonstrate this behavior the screenshots are here: after an order created (looks fine) click edit items and save updates (without any change), the result: What is wrong? Is it a bug? Thank you.
