I checked and at position "QT3-T/General Warehouse" there are currently 60 products (including 50 "Inventory Adjustment" products and 10 "Transfer" products).

But when I create a scrap ticket for that product at the location "QT3-T/General warehouse", Odoo reports a missing quantity.

I checked in pgAdmin, in the table "stock.quant", every time I enter stock +50, at the same time create an additional record with quantity -50, what's going on? how to fix it
