This is due to a responsive design coding that is configured to automatically hide that image when the screen reaches mobile size. This allows the page to better size for mobile compatibility.

Please note that responsive coding is out of the scope of support. If you'd like to have this changed, you will need to review the responsive coding that is hiding the image. If you would like one of our design service teams to assist with this, please contact your Client Success Manager or Project Manager to scope this request.
