PNP Search Results sort by title

Hi. I have a PNP Search results webpart, that brings me all the Document Libraries in SharePoint site (that are not the standard ones Like site assets, pages etc)

I want the results to be sorted, but i tried with sort column and it does not work, I want it to show in alphabetical order

If i use "edit sort order" and select by title, it gives me an error

I added a RefinableString where i have the title but it is still not sorting it

How can i get this list sorted without having to add another column for the Title (with out the link)
THank you
