Home Page Showing Private Post Entries

Hi, I wrote a post and published it. Then I made it into a draft and put it as private. You can’t see the post publicly, but my slider and my grid on my home page is still showing the featured picture from the private post and allows you to click to it. Of course, once you click into it, you can’t see the post.

How do I update the slider and grid to stop showing that post for people to click into?
