Hi,
Well, there is no trick here. I've used the URL that you provided :
Part of the message is hidden for the guests. Please log in or register to see it.
And the DC7 user account you provided.
Also, if you look at the affiliate URL, the one of your screenshot is for the user with the id 2 which is the user simplecms, not the user DC7 and the user simplecms has an affiliate sales total of 0 on the backend, so it matches with your screenshot of the frontend.
So to make it short, you're not logged in with the correct user and it's just a misunderstanding on your end.
