We have a 'weird' issue. When a customer order a product the inventory decreases by a random number.
Example. We have 11 items on stock, 2 orders are placed with a total of 3 items. The inventory decreases to -568.
Other products do the same, but with different numbers.
We checked all the extensions, but nothing is updating the inventory.
Inventory is filled trhough the import function of Magento.
Magento version: 2.1.7
