Headings and labels do not sufficiently describe a topic or purpose.
Text appears to be styled to look like a heading.
Recommendation
If text is meant to be a heading in style or function, use heading markup. Doing so will add semantic value to this text, which will let users understand the content's structure.
Heading tags should not be used to create visual style, it creates confusion for those who cannot see the visual style if the heading structure is irregular.
