There has been a name change happening when we release the Pro 5.x.x. These changes were discussed in our Monthly Report Status:
**So what is Cornerstone?**
It is a family of builders that includes our Layout Builder, Header Builder, Page Builder, Footer Builder, and Grid Editor. X users must install Cornerstone as a separate plugin and have access to the Page Builder. Pro users have Cornerstone built into the theme and have access to everything.
For more detailed information on why Pro and Cornerstone is now displaying in your dashboard, you can check out this documentation:
How did you duplicate the site? You should be using the Migration documentation to properly migrate those pages created in Cornerstone.
Because if you did duplicate the site manually, then this is why you are seeing those shortcodes in the pages and not the “Edit in Cornerstone” screen.
If you are seeing the shortcodes, chances are that the Cornerstone post metadata has been corrupted in which when you edit this page in Cornerstone, you’ll just be seeing a blank canvas.
When you edit a page or post in Cornerstone Builder, you will identify it by the type displayed next to the date.
