Homepage URL on menu bar problems

Using theme Webfolio v2.0.2
Using WP version 3.9.1
Website https://www.martyn-hitch.co.uk

Has anyone experienced this problem and knows how to fix it?
The ‘Home’ button on the menu goes to URL https://www.martyn-hitch.co.uk/home (I don’t want this, it shows nothing)
If I click on the logo, it goes to the correct homepage with the slider, https://www.martyn-hitch.co.uk
How do I get rid of the ‘/home’ from the menu item?

I tested the theme on my test site, all settings are identical and the problem does not exist,
the test site is https://www.pintofmilk.net

thanks
