Double header images in posts

I recently started using Newsmatic, importing all my old blog content from a WP Zoom theme (origin mage). For the most part I was able to customize and set it up the way I like, but I am having trouble figuring out a handful of things. The first is why the header image is showing up twice in all my blog posts! The link is just one example, it is on every post.

I also don’t know why my background color isn’t showing up behind all my homepage newsgrid sections: https://www.girltalkhq.com/

If anyone can help, let me know. I’ve also opened a support ticket to see if I can get customization help.
