header highlihgts don’t work on my site

Hello Skandha, I tried to implement the header hightlights, but i cannot get them working. If I choose for 5 custom items and there is only showing one. I cannot attach an image to header highlights. If I choose for "all post and pages" I see a kind of standard page and I can't change this page at all. https://drive.google.com/file/d/1TP83ZU17YCEombVH_suyDkZRaCzWDHsb I worked a number of times with header highlights of catchthemes, but this i didn't experience before. Can you please help? And i cannot add a link to this post, because the supportforum sais then: error: your topic cannot be created at this time. Kind regards Hans Hagmeijer
