Setting up Salary Sacrifice in Reckon Hosted

Hi I am trying to set up Salary Sacrifice of $100 per week but I have not set it up correctly. When I process payroll the pay slip the PAYG tax amount has increased and under Employer contributions it shows Hostplus 10% of amount (Employer contribution) and Salary Sacrifice-Hostplus as $100 but there has been no amount deducted from the earnings. Can anyone help please?
