Blog header does not pick the featured image. HELP.

Hi guys, I mentioned this issue before but I wasn't very clear. I set an "ARTICLE" page as blog page. I set every page (Home, Price, etc.) with a image header picked from feature image from WP edit page. I know the homepage will pick a video, and fall back to a image. However the blog is falling back to the same image as the homepage, and is not picking from FEATURED IMAGE from EDIT PAGE. I also notice that the header image does change (feature image) from every blog post...BUT DOES NOT PICKING UP THE FEATURED IMAGE FROM MAIN "ARTICLE"(blog page). I Need a URGENT help regarding to this issue. I'm about to launch the Website. Thanks
