Question about quotation marks in subtitle

I was just watching one of Julie's video's where she references her "Self-Promote & Succeed" book. She was talking about the title and subtitle and how they have to match, exactly. I noticed that on Julie's book cover, the words 'No Boring Books' in the subtitle is in single quotation marks but those same words on the Amazon sales page don't include the single quotation marks. If the title and subtitle have to be exactly the same why weren't the single quotation marks included on the Amazon sales page? Is there a reason why they were left out of the subtitle on the sales page?

Asking because I have a book that has quotation marks in the subtitle. They are on the book cover and I included the quotation marks in the subtitle on the Amazon sales page. Should I have not included them on the Amazon sales page?
