Large empty space below custom header on blog posts

I'm having difficulty figuring out how to remove the large space in each of my blog posts (on both browser and mobile) below the image header. I'm not sure if it's a custom CSS issue or something built into Squarespace that I can potentially edit. Any help would be greatly appreciated!

Here is an example blog post for reference: https://www.bookshop.love/bookshops/75

Thank you!

You mean this space?

Yes, it's much larger on different displays.

You can use this code to Website Tools > Custom CSS

/* Blog space */
.blog-item-wrapper article.entry {
    padding-top: 0px !important;
}
