How can I view shared Docs in Groups?

There are two Apps for viewing groups - one is through the Docs App where I am able to click on the group and i am able to view docs I have shared. 

However when I go through the Groups App to view a group this comes up with no documents found in shared docs? But i can see they are there if I go back through the Docs App into the group??

How can I get the docs to show in the Group App?
