It's not "missing", but it's your GK template which has control of it in the file /templates/gk_storebox/css/joomla.css around line 109.

By adding the following code to your CSS override it'll be back again:

input.hikashop_product_quantity_field {
  padding: 0;
  text-align: center;
  width: 34px;
}
