Ayush,
How many rows you have mapped to the scorecard?
If you have mapped 15 rows (for eg) then till 15 rows your scorecard is showing 15 lines correctly, but if there are more than 15 lines and you have not mapped it again to scorecard then how come your scorecard will display the additional rows?
Also you have to map your scorecard data in advance if you think your data can vary by time.
