“editor” role cannot see content in page editor

I have a website with “Enfold” theme. The pages use Avia Layout Builder for content. I need to set up a user as “editor” role to only edit one page on the website and not have access to edit anything else. I made that user the author of the page I want them to edit. This worked perfectly: they can see and edit that one page and not see anything else. Except all the content on the page is missing in editor role. I edit the page as admin and everything is there. I edit the page as editor and nothing is there. If I save the page as editor, all the content is deleted and the page shows blank on the website live. How can I get the content to appear in page editor for the “editor” user?
