Need help with pagination issue

I can’t seen to get pagination to work properly when I build a page with page builder.

Pagination works fine on my theme, I use it a lot, and it works great.

However, I’m now creating a post in page builder, and no matter what I try I can’t get pagination to work correctly. When inserting a page break ( in a row in the SO editor) or reverting back to WP editor, (it works) but either 1- the 2ed page is showing duplicate content of page. 2 – Even though the pagination is working it falls below all content on the first page and will not put the page break in the right spot. When placed manually in the correct spot, It cannot be seen in the SO editor. The SO page editor doesn’t recognize the page break. It ‘s invisible in the editor. So even when the page break has been inserted, it is useless to add additional content to the page because the page-break is non-existant within the editor. I tried several things to get it to work. Nothing is working.

Can someone help me with a real example ( step by step ) of how you get pages in a post with using SO page builder.
