Hi Fiona13
Sounds like you have identified why they are not appearing on that report and it's due to them not appearing on the payslip i.e they sound like they aren't accruing superannuation on the Pay employee window.
As the employee isn't accruing superannuation I would recommend checking out Help Article: Checking and adjusting superannuation which goes through checking that category and employee set up to ensure that superannuation is calculated going forward for that employee and therefore appear on that superannuation report.
