Do I uninstall Word Press?

I have removed all pages and returned to Theme twenty-sixteen and I have a recurring problem. When I add a page ‘Home’ I get followgarth.com/home/home/.
Same when I add page ‘About’ I get …/home/about/
Can you tell me where the problem is? I started getting this with Tesseract Theme, but it followed me back to 20/16.
Do I uninstall WP and start again? I use Bluehost for hosting.
