Adjustment u/s 143(1)(a)

i got communication for proposed adjustment u/s 143(1)(a) that says Arithmetical error in the return u/s 143(1)(a)(i), but i checked the calculation is correct. and incorrect claim u/s 143(1)(a)(ii) Schedule part BTI "The claim of set off current year loss shown in part -BTI is not consistent with the loss computed in the schedules of the corresponding heads of income or the priority of set off the current year loss is not consistent with the provisions of the act" 

if i choose submit button then choose agree
