No results using Toolset view filter

Hi,
I’m using the pro version of Relevanssi in a multisite built with Toolset. The main search seems to work without any issue but in the archive page https://centrodimedicina.com/professionista/ Toolset’s filters aren’t fully working.

In this page there’s a list of all the doctors working in the hospital with 3 filters at the top of the content. The third field “Cerca per nome o specialità” should let me search doctors by name and specialty but, if I type for example “allergologia”, there are no results, even if I’ve set that the text field containing this information must to be used in researches and in the filter editing panel I’ve choosen “search for Post content and title”. If I search by name the filter instead works.

This research is anyway working in the main research field: if you try for example to write “allergologia” in the grey bar with the placeholder “Cerca medico o altro”, the names of the doctors are shown correctly.

I added the code you suggest here https://www.relevanssi.com/knowledge-base/yoast-local-seo-compatibility-issues/ for websites that are using Yoast SEO plugin but it didn’t worked. I disinstalled and reinstalled Relevanssi but, again, without success.

Can you please help me to find what’s wrong with this filter?

Thanks,
Nicola
