The warehouse works somehow strangely ... (couples appear themselves)

Here is an example of a product https://vzutik.crm-onebox.com/admin/shop/products/26119/storage/ Here is an example of 2 orders https://vzutik.crm-onebox.com/admin/customorder/droperi/402959/edit/ https://vzutik.crm-onebox.com/admin/customorder/droperi/406388/edit/ They have the same product These orders passed the stage [file]12253[/file] The system goes to this stage itself when there is enough goods in stock, here is the action setting https://vzutik.crm-onebox.com/admin/shop/workflowstatus/555/action/new/ By history We see that the status changed on the 17th And if you look at the history of goods, you get something strange in general There were 0 goods, 2 pieces were credited [file]12254[/file] If you look at the quantity before the operation, then everything is going correctly only in the last operation something is wrong immediately written "before surgery" = 4 And now there are 3 positions in the warehouse, although if you look at the operations, it should be 0
