Making my blog my home page

I am self-hosting a blog using the Suits theme (blog.xa.co.za). I removed the “Home” page button as I intended my blog to actually be the home page and didn’t want an extra button.

This works fine when you land on the blog, but if I now click on the “blog” button, I don’t go back to the “Home” page any longer. Instead I am taken to blog.xa.co.za/blog. How do I get my blog button to connect me to my landing page instead of a blank page called blog.xa.co.za/blog?
