The shortcodes seem to be working inside Sections, they just have some HTML between them making the live columns display poorly. Have you tried removing the added HTML? Does it get re-added?
When the Visual Editor is turned off, it will be turned off inside Sections as well. I’m making some changes now so there’s no errors when the Visual Editor is turned off, and the sections will display the regular textarea with the toolbar.
Let me know 🙂
