EOY Payroll Submission - FBT S57A

Question on the end of year payroll reporting for an NFP and PBI. We pay FBT under s57A. 

When I preview an employee's payroll summary, it has their FBI amounts as "Salary sacrifice - other employee benefits". Is this correct?

If I select "Enable "RFBA" and put their salary sacrifice amounts, will this double count the FBT amount? 

Also, for employees that were terminated during the year, their amounts aren't pulling through, other than the PAYG withholding amount. How do I get this information to pull through?
