OK I have no idea why this was the problem. On the home page, there is a photo of a book with a drop shadow set to repel text. With the variant the main home page displays with the book stretched but not rotated, and the text is not repelling.
I converted the book to editable shapes and ungrouped leaving just the shadow to repel the text and now it displays correctly in the preview.
UPDATE: I brought everything back in Pro+ I was still having the problem with the hero photo not rotating. And not repelling.
I dragged the incorrect photo onto the desktop and noticed it was a WebP image.
I turned off the WebP option in Website Properties and bingo, everything is now working correctly.
