If a product has no ATS quantities set, Brandscope will display the infinity symbol inside the qty box.
If your product DOES have quantities set, but the infinity symbol is displaying inside the qty box, then the product's quantities are greater than the maximum display amount that your brand has set on the Brand edit screen.
Please check the amount set in the field called "ATS display amount" on the Brand edit screen: SETUP > BRANDS > EDIT.
If the "ATS display amount" is higher than your quantity amount, please contact a Brandscope Account Manager.
