Home-URL not showing correctly

[hemmi]

I just added your Xmap to my site.

Attn: I think this problem is related to that I am putting up a new website on another language and I am using... "mydomain.com/language" as the url.
(I am adding a fresh site there, not using a multilingual component)

The problem is this.
My sitemap shows everything correctly EXEPT the home url, the first url. There it is showing.... "mydomain.com/language/language" so the part "language" is showing up two times. All other urls are fine.

How can this be fixed?

Thank you very much!
