Class author-name

Hello, the author-name class on a post is showing up as a headline instead of 'author-name'. If you look at the home page, you will see the correct class, https://www.nspirement.com/
<span class="author-name" itemprop="name">Urian Buenconsejo</span>

But when you go the the post page it shows up as a headline, https://www.nspirement.com/2022/07/23/the-therapeutic-effects-of-indoor-plants.html
<p class="gb-headline gb-headline-0e23b4fa gb-headline-text">Emma Lu</p>.

Is there a way to have it show up as class='author-name'

Iam using dynamic content to pull the author name.

Thank you
