content in Muffin builder and it don`t display

After i create new page two thinks happen

1st

This harassing text  " Be is not limited to only one header style. At this moment we prepared 7
different header styles but with next futures you will see much more
possibilities. You can setup different styles, menus, icons and other
things. Also behind header, you can setup any background image you want.
You can upload one image the same for all pages or you can use
different header images for different pages."

I follow

"This option is useful for plugins like Yoast SEO to analize post content when you use Muffin Builder.
It will collect content from Muffin Builder Elements and copy it into the WordPress Editor.

Current Editor Content will be replaced.
You can hide the content if you turn "Hide the content" option ON."

Nothing change ....
