Pages saving PDF with thumbnails even when unchecked.

Is this something new...... I just made a Pages document, 3 pages long. I did not have thumbnails checked, nor could I see them when I made the document.

I want that Pages file to be a PDF. This work is for a client. So I go to file, print, and in that print box, I select save as PDF.

However, when I open that PDF it has thumbnails showing. When I go to view, they are clearly selected on the PDF preview, and I can't uncheck them.

The client does NOT want this PDF to have thumbnails.

So I tested this by making another Pages document with 3 pages of text only. I saved that. Then I saved it as a PDF, and that, too shows the thumbnails in the document. Again they were NOT showing in the Pages file (they were unchecked).

So why does it seem like all of a sudden, Pages is saving to PDFs only with thumbnails? I did this the other day with a different document and it didn't show thumbnails. What changed?

Again, when I open the PDF in Preview, it shows thumbnails, and I can not turn them off.

How do I get rid of the thumbnails??

A couple of images that show the pages file with no thumbnails. And then one that shows the PDF in Preview with thumbnails that I can't uncheck.

Help would be greatly appreciated. I need this file with NO thumbnails.
