"Header Options" in Blog-Item with no effect

My installation:
Skeleton “Blog Site” (Quark)
On the blog pages (template “Item”) you can find settings behind the tab “Blog Item” under the title “Header Options”.
Unfortunately I can’t find out where the setting “Display Header Image” has an effect.
Whether a hero image is displayed is determined in the “Hero Section”.
Can someone help me with this?
Thank you

@idna, Did a quick search in Quarks templates, but nowhere is field header.header_image being referred, apart from the blueprint.

So, I guess it is not being used (any longer)…

Thanks, I too searched the templates and came to the same conclusion. Then it would probably make sense if the developers delete the corresponding elements in view of a next update.
Thanks (once again) for your quick help and friendly atmosphere in this forum
