Hello,
It looks like your static block was created using Elementor, but changed to WPB content later. It causes the problem. I’ve created a new static block “test”, set your content, and selected for menu, it works – https://prnt.sc/zY6wsBx6uv7Y So delete the old static block, re-name the test one, and change it depending on your needs using WPBakery.
Regards
