Static homepage vs. blog – not sure what I’m doing wrong

Hello,

My site is located at https://www.sabrinagrey.com

I’m trying to set it up so that when you land on the site, the first page you see is a static WordPress page (https://www.sabrinagrey.com/about).

The site will also have a blog area, which I would like to house at https://www.sabrinagrey.com/blog.

Now, my problem is this: when I click the “Blog” link in my navigation bar, I expect to see my blog posts listed, but instead, I arrive back at the static page that I have set to be the homepage (https://www.sabrinagrey.com/about).

Can anyone tell me why this is happening? Thanks very much in advance!
