Buy Now Button Doesn’t Show

When ever I use a block with a “Buy Now” button, the button doesn’t show on the front end, even though it appears to be working perfectly find in Gutenberg. I’ve seen this happen across three different blogs now. Am I missing something? Why would it appear working in Gutenberg but not on the live page?

As you can see in the link provided, everything but the Buy button will show up on the post.
