Bajaj Finserv — Amount paid for 1year is not added to my principal loan amount

Loan id 508FGPGB911975 I'm paying emi since 2020 the amount I paid in the first year is not added to the principal amount. All the amount taken as interest only. My loan amount is 128000 but after paying for 2 years 4314 per month the principal amount is still 116000. How is it possible. I want my paid money to be added to my principal amount.
