Saving bank interest being taxed at 100% in itr2

hi

i am filing ITR2.

my saving bank interest income is 41000

i have entered 41000 in Schedule OS against field Interest, Gross.

and, i have entered the same amount under Schedule VIA with a purpose of taking the exemption of Rs 10,000.

my tax liability should be on amount 41000 minus 10000 = 31,000

my outstanding tax should be around Rs 9500

However, the Part B - TTI calculation shows tax payable as Rs 34810/-

can you please help me as to why this is happening

even if i try any number (say 2000) in Schedule OS against Interest, Gross, i see tax payable as 100% of this amount.

regards
