Two most likely issues:
1. This is language specific
2. There is a timeout or some other connection issue.
Is the category blank for all languages?
Also, if you check this in Chrome or Firefox and use the Developer Console do you see any errors?
After a closer look we may have had some issues around categories and subcategories.
Version 2.1 should correct those. If you install 2.1 and the issue persists please go into the CW World News settings and clear the cache.
Marking this as resolved since there has been no feedback to the contrary in a week. If the issue still exists please post back so we can investigate further.
