Category Link but no content?

Hello,

i have create to new types.For every type i selected the registered taxonomies (categories and tags).
Every type has one post and alls posts are marked to two categories from the registered taxonomies.

Now when i will click on categories it shows me: nothing found?

I have the same problem with tags.
When i click a tag it show me: nothing found, too ?
but the tag is marked with the taxamonie from the type post.

what is wrong?

sorry for my english.
