XML site map problem

I Maverick, here a problem with the Xml sitemap generated by the gpstool extension for xmap, as you can see in the images the link of the track didn't have the first part of the url so Googl webmaster tool sign all the path as wrong
In the images you can see first the correct one created for the native content and then the wrong of gps tracks
Could you put me in the right way to solve this issue?
thanks
Graziano
