I cannot select any links. Clicking on them does nothing

I'm trying to scrape the contact details of each company on this web page, see link below.
I start by adding the below link as the sitemap, and then create a selector with:

id: company_name
Type: link
Selector: Select, multiple
Parent: _root

The problem is that when I click on the company names to add them as a link selector, nothing happens. It doesn't turn red like the way it does on the webscraper.io test site. And the "a.category-link" selector doesn't show up on the "P.C.S.Done selecting" bar in the bottom left.

I've tried with both Arc Browser and Chrome.

Can someone check out that site and check to see if there is some sort of tool blocking me from selecting a link.

Thanks!

Try this sitemap :

{"_id":"Test","startUrl":["https://www.irishtrade.ie/category_list.php?view=3&cid=38"],"selectors":[{"id":"Link","linkType":"linkFromHref","multiple":true,"parentSelectors":["_root"],"selector":".row.align-items-center > .col-md-4 a","type":"SelectorLink"}]}

And your link selector is : .row.align-items-center > .col-md-4 a
