Block Doesn’t Generate on Live Page

I created a simple custom block (two textarea fields, wrapped in some div tags). It shows up correctly when editing a page.

When viewing the live page, it doesn’t show. Using the inspector, I can see it’s outputting as a comment and not actual tags:

<!-- wp:genesis-custom-blocks/continue-reading {"first-paragraph":"Content here","additional-paragraphs":"Content here"} / -->
