Default language not appearing.

I am using WordPress 3.8 and Polylang 1.3.1, but for a few versions, I have not been able to view the English page as the default page for the site. I have three languages set up: English, Traditional Chinese and Simplified Chinese. When I visit my site (https://waiyindemo.cocode.org.uk/) I appear at the Traditional Chinese page, even when logged in. My language is explicitly set to English (not “default”), the site’s default language is set to English, and yet it comes back to me with the Traditional Chinese page. Can anyone help me?
