Unfortunately your post doesn't provide me with the exact details as to what is happening. Can you perhaps explain the issue or even record a short video showing the issue ?

I would recommend not using this since this is now our legacy plugin and to continue with just using our Blocks plugin as the documentation is tailored for the use of our Blocks plugin.
Do you plan to make use of our Layouts plugin ? If not then you can disable it and then follow the instructions exactly in our documentation to resolve the issue.
The problem is being caused by the use of Layouts.
