Under Category wordpress doesn't pull out anything from CPT

Hello,

I have a sidebar with category section…if I choose the category created to be use with all post in CPT I just see a blank posts..

I'm uploading 2 images to show you the problem. The first image shows one of my post created in the CPT called 'be creatives' and second shows the display made under categories where it doesn't show the post.

Any ideas??? I would very thankful

Cheers,

Jose
