Payslip not showing employee salary figure

Hi, I have an issue with the payslip, the salary on the payslip for 2 employees reflects M0.00, is there a way to correct this? I have added total of 4 employees but the payslip only shows salary for 2 employees

You can try to compare the employees with correct payslip result with the ones that cannot show correct result, see which part you did differently.
