The Product Performance dashboard displays a calculated value for the Organic sales column. Ad Badger only fetches the "Total Sales Value" from Amazon and computes the Organic sales by subtracting the Ad Sales from the Total Sales. 

In case some sales are not fetched (not AB fault), this calculation could result in a negative number. To prevent negative values from appearing on the dashboard, the organic sales column will show zero if the Total Sales are lower than the Ad Sales. It's important to note that the Organic Sales column is a calculated value, and a zero value does not necessarily indicate the absence of organic sales.
