Hello,
Are you talking about breadcrumbs image and about breadcrumbs texts http://prntscr.com/v556m5 ?
You can disable them in the page settings http://prntscr.com/v558p2 If you want just to change the image upload the new one using page features image.
Knife image is the image from the page content, edit page and just remove the first image.
Regards
