User Karma Profile

Hi,

I am using the module drigg.
I would like to know how to change what appear in the user profile under the "view" tab.
Even if I tick the boxes:

Show ranking in the user profile page
Create a "karma" attribute for a $user
Create a "rank" attribute for a $user

i cannot have the box appears in my users' profiles. I cannot have the user stats neither!

Thank you so much for your help,

Pirch
