I tried to import the demo data...

I had it running for a while, then it stoped. Doesn't look like it makes any difference.

What am I missing? Thank you for your help!

I now installed a brand new instance of WordPress.
I then imported the demo. This worked.
I tried to bring a page from this demo over to my client site.
Following some instructions online I managed to export a page and then import it on the target site.

This seam to work via .json files. 

First Issue:

When looking at:

https://neuronthemes.com/kanik/about-us/ the online demo site

vs 

https://dev-kanik-01.pantheonsite.io/about-us my fresh instant with demo import

the page looks different, it has an additional About us headline

How can I delete this?

The looking at my target site
https://dev-augustlaube-07.pantheonsite.io/test-01/

I imported the page into the existing site.

As you can see the visuals are different....

How can I move forward with this?

Pls let me know what I am missing.

Managed to fix the About page by going back in revisions.

Still don't know how to apply or not apply a header to a specific page...

Anyway I also went back on a backup on the target page.

That is the page that I actually want to create.

Again I tried to import the demo... not possible.

Is it possible to bring in specific pages?
