Custom taxonomy archive page

So in this article: https://www.hotel*****.co.uk/14342-accorhotels-to-remove-plastic-straws-by-june/

The word AccorHotels is automatically linked, But when you click on the link, it goes to a random AccorHotels story from the past.

It should be loading as an archive of all posts that have this tag in custom taxonomy applied. Why is not opening an archive page?
