Unable to pick a grid layout

I installed the plugin today, and this is the only problem that’s come up. I assume I should be able to trigger a dropdown menu as I can in all the other sections, but it doesn’t show up.

I’m stuck with a single column in the front end; https://library.mirthfulconfusion.com/post-grid-test/

Other than that, this is a wonderfully comprehensive UI, many thanks
