All of the theme elements (header, footer, menu etc) are stripped on the page that isn’t working.
Looks like they are removed by the page builder to be a canvas (like Elementor canvas)
I don’t believe there is a solution for this as it’s meant to be a canvas and let you start fresh.
I would recommend checking with their support to see if there is a way to keep certain elements from the theme.
Let me know if this helps 🙂
