You may be right.
This: block-library/style.min.css
is the core block styles CSS which should contain CSS for several column classes for the latest-posts
Whereas the CSS file on your site does not.
And heres that stylesheets URL
https://bondscenes.com/wp-includes/css/dist/block-library/style.min.css?ver=6.2&ez_used_css_s=112
And see the query string: ?ver=6.2&ez_used_css_s=112
thats what ezoic adds after it has been through their critical CSS optimization. You may just need to regenerated that CSS.
