Negative balance for a product in stock

Hello. We faced a problem - the product had a negative balance in the warehouse. It happened, apparently, due to the simultaneous operation of several return operations in this task https://zavod.crm-onebox.com/admin/customorder/order/289201/edit/ Deleting warehouse return actions does not work - the system writes that everything went well and will be processed within 2-3 minutes, but nothing happens. In the "Doubling Operations" screenshot, a red rectangle indicates an action that looks especially strange - when trying to "return a product", the "return quantity" field is set to -120. I ask you to correct the situation so that we can work with the product through the warehouse again. [file]12931[/file] [file]12932[/file]
