The physical stock of products is automatically incremented with each order

[tkoutils]

Hello,

We have just migrated our site from PrestaShop 1.6.1.16 to Prestashop 8.2.3 using the Migration Pro module, but since the migration, we have encountered a strange problem.

As soon as an order is placed, the physical stock of the products included in that order is increased. If three products are ordered, three products are added, and so on.

This problem occurs with any order, regardless of whether the item is in stock, the carrier, or the payment method. It is also not related to the order status, as the problem occurs as soon as the order is placed, whether it is pending payment, paid, or otherwise. By the way, this change doesn't print any stock movement.

We have tried disabling the modules, but nothing works. This problem is having a major impact on our stock and is starting to affect our services.

Does anyone have any ideas? We are open to any solution.

Please let me know if you need any further information.

Best regards,
Theo Marchal
