The Main Blog Page is listing all blog titles in H1

Hello!

You guys have helped me before so I was wondering if you can help me again.

The main blog page where it lists out all my individual posts keeps making the title of the blog post to be an H1 when it should just been an H2.

Does anyone know why and how I can fix this? This is the first time I am even aware this is possible. I am using GeneratePress theme and Elementor. The blog posts is imported for the live site but there is nothing customized about it.

Thank you as always.
