Hi, I can’t work out why my archive page link is not working. I’ve changed the name of the “Posts” post type to “Case Studies”

I can see a preview of it here https://shelfspan.dev.anzu.nvisage.co.uk/?elementor_library=post-type-post-template-archive

But when I add a link to it with @site(post_types.post.archive) it results in a link to the homepage or it might be redirecting to the homepage.
