Zeff,
How are you accessing the page? From the "Pages" sidebar? Or do you have XBlog configured to show "All Pages" or a certain page on the home page (as opposed to "Blog"). You can find that info in the Layout document\Entry Tab\Home Page Contains field.
I've been working on this and if XBlog is configured to show "All Pages" or a particular page on the home page, the navigation works. So I'm just curious as to how you're getting to the page that has the broken navigation.
