Magento 2.3.4 salable quantity and default stock problem with one product

Question

My version of Magento is 2.3.4 One of my product shows default value stock = 15, when true stock is 0. I have checked the database and it's look like this.

mysql> select * from inventory_reservation;

| reservation_id | stock_id | sku          | quantity | metadata                                                                  |
