Fix duplicate blogs

I’m not sure how I did it, but there’s now two sets of blog posts on my blog page.

I have blog posts in a grid on top, which I made using the visual composer, and a second set of blog posts beneath the grid, which I don’t know how I made and which I can’t figure out how to remove.

Here’s the page:

How can I remove the second/bottom blog?

Thanks!
