IRP5 not showing Code 3701

I receive Travel Allowance monthly and on my IRP5 it does not show as Code 3701 but rather showing as 3703. How does one go about with this issue as this Allowance shows on my payslip and added to gross earnings and thus taxed.

This is not a travel allowance, but a travel reimbursement which is not taxable. You do not need to do anything with it.
