I paid the principal in advance. Why does SMS show loan principal and interest?

Generally, the repayment terms of banks will choose the repayment method that is beneficial to banks. If the principal is repaid first, the bank will get less interest. Therefore, the bank will repay in advance in the order of late payment fee, interest and principal. Unless you have special terms when signing a contract, customers will not have special terms when signing a contract, which is beneficial to banks.
