I work on a wordpress website for a client of mine: https://kallies-automobile.de/.

There is an overview page which shows all available cars: https://kallies-automobile.de/fahrzeugangebot/. This one is using a custom template I made with Elementor. Now you can use a filter, to filter down the stock of cars. If you’re searching for cars only manufactured by Nissan, you can access them also directly via https://kallies-automobile.de/fahrzeugangebot/NISSAN/.

The problem is that I can’t create a separate page for Nissan. It will show the default text from the parent page “Fahrzeugangebot”.

I want to create separate pages for every car brand available with a custom text etc. When I create the subpage “Nissan”, it isn’t editable and redirects back to the given archive page.

Any ideas what to do about it?
