extra blog page

I have an ecommerce site that has one page as the blog page and the rest show my products. I’ve noticed that, if I do a search for my blog page, I get one page that works and one that goes to an error page. The working one is gardenandsoul.com/blog and the error one is gardenandsoul.com/garden-and-soul-blog. How can I get rid of the second one? Thanks.
