After further testing: it is only the Home menu item that does this. If I remove the home page from the menu then the menu works as the demo. If I move the home page menu item around in the menu so it’s not the first item, it’s still highlighted in the menu. So it’s the home page that’s the problem.
I have it set as a static front page, but can’t see anything different with it.
I deleted the page and created another. When it was just a page added to the menu it was fine. As soon as I made it a static front page I had the problem. So it seems to be an issue setting the homepage as a static front page.
many thanks
