More rating in correspondence

Today , I won a game in correspondence and won 21 points. But when I opened my profile, under activity It was showing that my rating has increased to 1541 but under the rating table on the left - hand side of the page it was showing that my rating has increased to 1552. Why was it showing like this?

cuz it's correspondence. (system confuses itself cuz games take more than just a day and are played simultaneously)
