Quantity Imput-None doesn't work

-- HikaShop version -- : 3.5.1
-- Joomla version -- : 3.8.11
-- PHP version -- : 7.0.31
-- Browser(s) name and version -- : Firefox 61.0.2

On a particular product I do not want the quantity box to show. I set that product's Display>Quantity Input to None, but it still displays. I tried switching to the Prostar template and it still is showing on the product page.I also tried the various Input settings to no avail.What am I doing wrong?

Hello,

Can you check that you don't have any customization of files of the "Product" view of your front-end template via "Hikashop->Display->Views" and try it without it ? Thank you.
