search_category

Hello,
I would like to know how to display store that sell a particular product which has been catalogued with a specific category. In particular, I would like to display all stores that sell “fruit” (frutta in italian). I typed this but I get a list of all stores even the ones that do not sell fruit:

[wcfm_stores search_category=”frutta” has_product=”yes” has_radius=”yes”]

Needless to say that the category “frutta” exists.

Thank you
Kind regards,
Dan
