Income Tax Slab not picking

Hello

I am facing a problem with the payroll income tax slab. I have an income tax slap and a salary component named PAYE which is a deduction and has “Variable Based on Taxable Salary”. The Basic Salary is the only Taxable salary. This PAYE component is not showing in the payroll. I want the PAYE component to be calculated from the Basic salary by using Income Tax Slab.

Thank you in advance.
