Xmlsitemap not recording full url?

In my site I have one main page titled appropriately enough "main". This page is composed entirely of views that receive arguments (i.e. "/alabama/abernant"). When a user selects "/alabama/abernant" the arguments are fed to the views and updates the page "main" accordingly. The full url for the "drilled down" page is thus "www.xxx.com/main/alabama/abernant". What is happening is that xmlsitemap is creating the urls as "http://www.xxx.com/alabama/abernant" minus the /main. I didn't recognize this issue until just recently and now I've got a bunch of incorrect url's on Google that I'm going to need to fix somehow (but that's another issue entirely). Did I miss something on setup here or is this just the nature of the beast?
