Category linking back to home page (or not!)

Hi

I have a set of categories. One of which ‘Home page’ I want to link back to my um, home page, but its linking instead to the category summary for that category. (nb the site is not live hence the false sitename that follows!)

https://www.site.org.uk/?cat=8

when I just want it to go to

https://www.site.org.uk/

I can see why it would do what it’s doing, but I want a link in my navigation ‘home’ or something similar, that will just take me back to my home url!

Hope this makes sense and someone can help! Thanks for reading!
