Hi,
There is no duplication ; like I told you in my previous post, because the product is in two categories and you display "all sub elements", HikaMarket display them all and it display the items each time it found them ; so it is a """""""display duplication""""""" (with a lot of quotes).
Just changed your filter "all sub elements" into "direct sub elements" and the display will be fine.
It will be fixed in the next HikaMarket release.
