PB CK only shows {pagebuilderck 11} instead of content

I am building a page where I want to display a Pagebuilder CK item in a Custom HTML module.
It works fine in other places on the site.
But it won't load.
Only {pagebuilderck 11} appears.
Even when I load an already working item from PB CK on that module position, no content appears.
What could be causing this?

The template has three modular positions at the bottom, Footnav-1, Footnav-2 and Footnav-3.
It's about Footnav-3.
The website is:https://campingterasy.nl

Hi
in the module >> advanced >> prepare content >> YES
