Customiser and full navbar

I am editing the Blocksy theme using the Customiser. For some reason, when I am editing the Header in the Customiser, the navbar remains a trigger/hamburger-even when in desktop tab view. I cannot see all of the nav links in desktop view-it remains a trigger hamburger. This makes it very hard to edit the navbar and header.

The navbar show normally when the website is opened via the server-it is just the Customiser the desktop nav wont show. I have tried deactivating all plugins and clearing history and the cache but this does not help.

Any tips or suggestions would be mostly appreciated.
