Adjustment of previous STCG against current year LTCG

I have previous year STCG loss of Rs 47000 .This year also STCG loss is Rs 60000 so total loss CFL should be 107000. Also this year I have LTCG of Rs 10000 which is not taxable upto 125000 But while filling income tax return the software of Income Tax online e-filing reduces Rs 10000 from my current year STCG loss of Rs 60000 and shows net loss as 50000 hence total loss of 47000 + 50000 = 97000. My question is if the LTCG of Rs 10000 is not taxable then why or how it is adjusted against my STCG? This way I am not getting the benefit of exemption of in LTCG. I had put grievance on incometax site but still I have not received any response from them. Please guide.
