Problem with permalink shop

Hi there

If I change the permalink, setting “shop base with category” and save (http://www.ditoma-abitiprofessionali.it/2.png), the setting is not saved (http://www.ditoma-abitiprofessionali.it/3.png) and the name of the product category doesn’t appear on the URL. (I don’t see for example “shoes” but in the URL appears generically “categoria-prodotto” see http://www.ditoma-abitiprofessionali.it/1.jpeg).

Best regards
