CTA button is tagged with H1 somehow. How do I remove it?

According to our SEO checker, we are scoring very low (38%) on Page structure because it says we have two H1 headings on our Homepage.

One is the correct H1, but the other is the “Request a demo” CTA button.

How can i remove the H1 from this CTA button?

Thanks

Nevermind. It was the ensuing pop-up that was tagged with the H1 tag. All resolved.
