No category with CB Blog set to Joomla and K2

Hello
I am a new user of community builder and find it as a great program. Trying out the functions I found a problem with CB Blogs. If I set the blog model to Joomla or K2 it is not possible to select a category. Categorys are created in Joomla and K2. Also subcategory. In both cases the dropdown field for category is empty and without a category the blog is not stored. At the admin site the selections are available.
Is there a additional setting for activating this feature?
Thank you for a feedback

Thank you for the quick answer and sorry for not guiving all informations.
The joomla version is 3.3.6
Community builder version is 2.0.6
PHP5 and Mysql5

I have seen the two tutorial videos and followed step by step. But on the frontend there is no category selection possible.

You need to create a tree structure for your K2 Categories.

Something like:
Cat1
--Cat11
--Cat12

Then select Cat1 1 in your Blogs parameter in backend and that will allow people to select Cat11 or Cat12 in frontend.

Thank you very much
I had the cat-structure in this way.
The error was not to set the main cat1 in the blog settings but directly Cat11.
Now it is solved.
Great support
