header featured image cannot be turned off

Hello Skandha, I attached a few images. I cannot turn off the header featured image. And we don’t need a header featured image on each page. Particularly not in the for members accessible part of the website. What I did:

1. I configured the header media as: enter site, page /post featured image.
2. I adapted the lay out options Single page/post image lay out disabled
3. I disabled the header featured image options on the page
4. The result: a page with the header featured image and a cover image

Can you please tell me how to turn off the header featured image. Kind regards Hans Hagmeijer
