Hiding Feature Image

Hi,

Really great theme. I’ve been able to customize it a good bit. Been working on a draft blog, for my future travel adventure.

If I set an image to featured, it displays nicely, but then down below it repeats itself. So essentially it’s a duplicate post/image. How do I make something that is set as a featured image, not repeat itself? Thanks? In development: https://meh273.org/
