I am trying to include Covid19 sickness absence for a member of staff.

I have followed the instructions and used the advance option to set up the statutory sick pay for this employee with no waiting days and it appears correctly on the employees page, however when I go back to my payroll and look at the employee's payslip, it does not appear there. The message on the employee's page is "You can utilise this screen to add, edit or delete (if available) statutory payments which will then be applied automatically to the pay run." But that is not happening. Do I need to delete and then recreate the payrun to get it included?
