Different views of a product produce different stock quantities.
The stock count generated via the button in the product list view and the list view itself both present out-of-date stock quantities, while the product export, product detail and product inventory log all have up-to-date info. This makes stock counts and tracking down discrepancies extremely difficult, as problems are only discovered after the fact, and it leaves one wondering how much the data can be trusted.
This really needs fixing.
