Error "total of quaterly breakup is less"

I have purchased shares for amount 396286 and sold those at amount 444924 and repurchased shares of same configuration and amount as Short Term Capital Gain is 48638 and I have reinvested this amount also in shares. But when I fill the column 2 of Sch CG it gives me an error "Total of Quarterly breakup in STCG 15% is less by 48638", why is this error occurring and what should I do to get it rectified.
