I’ve checked the markup and the BB styling for that layout is loaded. This can also be verified with how the columns are staying side by side, not on top of each other - this is done by CSS. The problem here is that the theme you’re using has a different styling for pages and posts, that’s why it looks different on the latter. Here’s a sample styling which can be found specific to pages…
It’s only targeting the body class dynamik-page-builder which I believe only appears when you use the Page Builder page template. The same styling is not applied to posts, and this is the reason why the texts are so close to each other.
