Problem with home page and blog page

Hello

I am using Clea retina theme for site https://www.josejoaquinlama.com.

I am almost finished but got a problem:

The blog page has become the same as the blog page ( you can see that ‘Novedades’ is the same…

This is annoying because I would like to have a blog where I can add posts.

Any hints?

Thanks

P.
