I have enabled the partial delivery option in configuration and average price perpetual inventory valuation. Today, I check the inventory valuation and I see that there are duplicated POS00050 stock move but of course there is just only one stock in operation as follows

The second stock move is caused by validating a partially availability transfer of that order POS00050 too and so cause duplicate stock valuation which also cause wrong quality on hand. However, when I check the product in Operations > All transfer, there is only one operation of that product captured below

What wrong with this? Or I have wrong configured anything?
