Blog – Yoast says I have 0 text on my blog page

I get this message while editing my blog page, not the post.

“The text contains 0 words. This is far below the recommended minimum of 300 words. Add more content that is relevant for the topic.”

I will never have text on my blog page that I know of, except for the title, “Blog.”
All the text goes into the post which is published to my WordPress blog.

Is this something yoast did not account for?
