I enabled the plugin.

1. I created a fields group
2. In the fields group I added 1 field that I wanted to be displayed in the blog post backend
3. The tab appears in the post ,but when I click on it I see button "create new element"
4. After clicking on it I see my field but all meta fields inside also.
5. Below of those field I see another button create new element

This is the fault of the Seo plugin developer. When he extending the form he did not add validation of nested widgets

Ok so You mean the issue with fields from meta. But the question is also about how I can add field to blog so I wont need to add some kind of repeater. Just one extra checkbox field?

What specific SEO plugin are you using? To fix it, only need to add one line of code.
