Popular with your friends

I have another question with Instant Articles. When I look at an article that is correct, shows all the correct images and even the Network Audience ads are there. When you scroll down after the article, there is a section titled “Popular with your friends.” Here I see other articles that have been submitted from my website but the problem is the picture they are showing on these little “suggestions” blogs have nothing to do with the blog itself.

Actually, the image is an advertisement that resides on the site. It shows up for multiple suggested articles, but there are a couple that have the the correct image from the article, so I’m really not sure how to fix this one. Anyone have any ideas?
