Woocommerce Product Filter include in taxonomy terms not in relationship with page results

Today i just visited a page on my site : https://www.outletscarpeonline.it/brand/demonia/

what i see is that in the filter “taglia” and other filter, include all list from taxonomy and not only taxonomy related to results of a page.
How can i mod this error?
infact if you see this page you can check that “taglia” results “L” is not a taxonomy of this results!
How can i make this filters work only in relationship with page results? Any suggestion?
