A few functionality questions

I have a few questions regarding the plugin re: https://theyrenotcankles.com/find-a-lipedema-specialist

1. When I click on category listing (i.e. Compression Retailer49, Lipedema Surgeon129, MLD Therapist107, Vascular Surgeon) under the search box and above the map I get a 404 error. Shouldn’t this provide all of the listings that fall under these categories when I click? How do I fix the 404?

2. When I click on any one of the individual listings under the map on the main search page it loops me back to the search page. Shouldn’t it open the page for the individual listing? How do I fix this?

3. I selected ‘default order by’ Title and the listings under the map on the search page still appear to be randomized. They are not in alphabetical order of the title. How do I fix this?

4. Is there a way to import country and state fields with a csv spreadsheet import? I’ve put the fields in my spreadsheet but there’s nowhere to map them so they automatically populate on the individual listing page.
