Page Header options changed? not shown on edit-post anymore?

Hi,
normally I used the page header function to include my picture slider to the post, like this:

But today when I tried doing this it looked different, saying "no page headers found"

When I look at the Page header video here on generate press it seems like this function is gone now and I have to create all headers in "page headers" and I cannot just simply put them under my edit page content? Or can I somehow get back the page header option in my "edit page and post" like it used to be? My old posts still have this option (like in first screenshot).
Someone knows what to do?

Best wishes
Yannick
