You may notice that there are two figures in your Home page. Here's the difference between them.
The dark blue figure
This number is the total you have collected from only completing Surveys, Hot Topics, and Quizzes so far. Any special points awarded to you - such as lucky draw bonus - do not contribute to this amount.
The light blue figure
This is the total you have accumulated from completing activities (Surveys, Hot Topics, and Quizzes) plus any special points credited to you by milieu during campaigns, lucky draws, etc. This is the amount you can use to redeem your rewards.
