XML Sitemap displays only first menu

[Cony]

Xmap 2.0RC1, Joomla 1.6.3.
Create sitemap with two menus, and check the xml sitemap, only the first menu is displayed. I have no menu for this XML sitemap, just using direct link ?option=com_xmap&view=xml&id=1

Ok, after playing around I found out that it is not rule, that only first menu displays. Finally I have 4 menus included, and only in one combination of ordering all aitems are displayd correctly. If I move some menu to another position, not all items are displayed.
