Smart Search always returning results to component, not the defined new page

[bdam]

I've followed the steps here to set up Smart Search on a J 3.8.2 site: https://docs.joomla.org/Smart_Search_quickstart_guide
I created the Smart Search module and assigned it a position "smart-search".
I then created an article with just the content {loadposition smart-search}.
I then created a "Search" menu item pointing to this article, it's url is just /smartsearch-2, then went back to the module and set its ItemID to the new menu item.
When I select the menu, it takes me to this custom search page, i.e. my new article (/smartsearch-2), but when I enter a search term and click the search button there, the results are to what looks like the component page itself, i.e. the url is /component/finder/search?q=&Itemid=246.

I was expecting the search results to go back to that search page, i.e. /smartsearch-2, since that's what the setup guide says it does.

Have I misunderstood something here please?

The site is https://www.phonewebcam.co.uk

Thanks!
