Infinite SEO - putting non-existant page into SiteMap due to sud-directory install

I have installed Wordpress in a sub-directory: http://www.duoplus.co.nz/site/
I have then followed the steps to get my Wordpress install to show in the root directory. http://www.duoplus.co.nz This works fine.

However the site map generated by Infinite SEO has the highest priority page listed as http://www.duoplus.co.nz/site - which doesn't exist! It gives a 404 error. Because my site is displaying at http://www.duoplus.co.nz

It has the other correct URLs for my site. But it has my homepage as "weekly" to check, and this non-existant page as "daily".

How can I fix this please?
thanks
Josh
