Hi when i check the black jacks scores i have 2000 which is correct.
but when i check the rankings it shows my ranking is 31 or 32 with the score of 30250 points, which is completely wrong. i just have 2000.
Could you just look into it when you find time.

It is probably due to caching. The classements aren't updated in real time. You probably had 32000 a few hours before you checked.
