You didn't specify your Sitefinity version, so I tested this with 3.6 hotfix and could not reproduce the problem.
However, if you want to make your news items appear in a new page, you can use the SingleItemUrl
property on the NewsView that will display all news items, and ItemListUrl
on the NewsView control that will display the single news item. These properties actually point to the pages
If you want to generate a separate page that will show content item in details you should also have NewsView control on this page.
The public controls are explained in greater detail in the manual
