Although with a classic breakdown, you can make 12 columns

And even 14 columns

Do you understand that already created and configured columns will break if you add columns to them through the row settings?

And your addon "Column" does not allow you to add even the 9th addon

Hi there,

I appreciate you reaching out. I sincerely apologize for this oversight. You can use 12 column after that your column will go under the first row. Check the screenshot.
