Strange h tag structure

[MaDoGK]

I'm helping a friend with his Shopify page. The site has a strange h-tag structure. For example, the add to cart pop-up shows with an h2 tag 'Just added to your cart', which is the very first h-tag in the source code, followed by an empty h3 tag, and then the logos are set as h tags. Here's the h-tag structure:

I thought this was a problem with his site, but when I checked the debut demo site, it has the same problem.

We manually edited the source code, removing the h tags, but then the shop started to act strangely, so we had to revert back to the old setup. This h-tag structure isn't great for SEO and I'd love to correct it. Is there a way to correct the problem without breaking the page?

I see the report on https://validator.w3.org/

You could fix the h1>h2 first error by changing code to

It would be enough for good h SEO and resolve your issue. I don't find any bugs after.

You could push the change to PR and I'll merge it into the repo.

Let me know if you have any more questions, otherwise, you can close the issue
