i use Prestashop 1.6.0.9 , default theme, nothing modified
sort asc product ( e.g. price:lowest first, product name: A to Z ) working properly
but sort desc product ( e.g. price:highest first, product name: Z to A ) not working properly ,
sort desc product result :
$10.00
$12.00
$15.00
$22.00
( sort desc product displays the same results as sort asc product)
This problem also occurs on the prestashop demo page http://demo.prestashop.com/en/?view=front
how to fix this problem?
