Hi gerhardfjvr ,
Apologies for any inconvenience caused.
First, you talk about variations in your text, but you included screenshots of a simple product, and none of them is from the Inventory tab.
Also, please note that the Current Stock Value widget is calculated from the Purchase Price values, never from the Sale Price, and I can see in your image that you have 2829 items without the Purchase Price set.
Best Regards,
José Andrés
