Disable default Characteristic is always selected

-- HikaShop version -- : 4.4.1
-- Joomla version -- : 3.9.25
-- PHP version -- : 7.4

Hi,
I've a bit of an issue. When I have a product with only one characteristic, then this characteristic is always selected (image-2). I would like this to be changed to "Please Select" so the user is forced to take a look at the characteristic before the add to cart button is pressed. Strangely, when I have 2 characteristics this is default behavior. Even the button is removed until all selections have been made. Image-1

How can I set this up if I only have one characteristic?

Thanks!
