Failed to Import H1 from Article; H2 works

Hi. I am trying to import this article: https://tinyrituals.co/blogs/tiny-rituals/conscious-connection-whats-my-moon-sign You can see that the headings in the article are h1. Everything is imported to my wordpress installation except the h1 headings in the text.   When I try to import this URL: https://tinyrituals.co/blogs/tiny-rituals/cleaning-sterling-silver from the same website you can see, that the headings are H2 tags. And all of the H2 headings are imported correctly.   So sorry for this dumb question: But why I cannot import H1 tags from article 1. Instead H2 tags from article 2 imported correctly? Thank you in advance
