Why would an employee's medical aid employee deduction component reflect as a company contribution?
An employee's medical aid employee deduction component will reflect as a company contribution if the component has been marked as "in package".
Edit the component and disable the checkbox so that the component is correctly reflected as a deduction.
Navigate > Employee > Payroll Processing > Recurring Payroll Components > Company Contributions
To have the component reflect underneath Deductions, select to edit the component on the Recurring Payroll Components screen and remove the "in package" component.
