/home instead of /en

On live install here:
http://www.webid.co.nz on some browsers it defaults to http://www.webid.co.nz/home (404 error - doesnt show on site error or Litecart error log) on others it goes to http://www.webid.co.nz/en which is the right one.
This happens after deleting browser caches regardless.

Ive tried combos of .htaccess none have worked on redirect.
Anyone had similar and fixed it?

It should never default to /home.

These occurences are valid though:

/index
/en/index
/en/
/index.php/index
/index.php/en/index
/index.php/en/

Controlled by lib_route.inc.php and url_index.inc.php.

Dont know how, but by using a secure redirect seems to have fixed the problem:
.htaccess

RewriteEngine On
  # Web path to catalog root
RewriteBase /
RewriteCond %{HTTPS} !=on
