Faceted filters also out of stock items

[chemocycling]

hi

when i use faceted filter in search results show all items (both stock and out of stock ).why ? 

 

 

for example i sell shoes and  when i filter shoe size 48 all items shows (in stock and out of stock )

 

how can i filter and show only in stock items ?

 

thanks

There should be an in stock/out of stock filter too, did you enable it?

yes i have both filters enable but all products appear

All products still appear if you click on either checkbox? That's very odd

Hm, I don't think it calculates both options, it probably only checks if it's generically out of stock (all combos)
