Breadcrumbs error category

Hi there,
I have a problem with breadcrumbs URL for the category.
In the source page, it seems right:

@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"https:\/\/fumolento.af1.it\/","name":"Home"}},{"@type":"ListItem","position":2,"item":{"@id":"https:\/fumolento.af1.it\/balmoral\/","name":"Balmoral"}},{"@type":"ListItem","position":3,"item":{"@id":"https:\/\/fumolento.af1.it\/balmoral\/balmoral-aejo-xo-gran-perfecto-ft-edicin-limitada-2018.html","name":"Balmoral A&ntilde;ejo XO Gran Perfecto FT Edici&oacute;n Limitada 2018"}}]}]}</script>
<!-- /Rank Math WordPress SEO plugin -->

but in the link returs two times the URL’l website, I link the screenshot.
Thanks in advance.

The page I need help with: [log in to see the link]
