The headline tag is present, but it does not contain a headline.

Why an empty heading fails

An H1 is useful because it says what the page is about. A blank tag gives screen readers a heading stop with no label and gives search engines no phrase to connect to the topic. It can happen when a template renders the heading wrapper even when the CMS field is blank, or when styling hides all text from the tag.

What to fix

Put the real page headline inside the H1, then use H2 and H3 for the sections below it. If the page does not have a clear headline yet, write one before publishing instead of leaving an empty element in the document outline.
