Feeds category terms links to empty pages

Hello,
i created two feeds (for two different rss urls).
I assign each feed to a different category (from "Category Feeds vocabulary") eg. news and travel

The module seems to work fine, i mean it gets posts into feed items and each feed item has the appropriate category term selected ( checked on edit)

When i go ..admin/content/taxonomy --> terms and i click on a term this redirects me to an empty page, while it should redirect me to a list of all news or travel posts

If anyone can help,
mike
