How do I make new element appear on ppar and payslip?

Summary:

I’ve created a new payroll element. It’s purpose is to increase the employee’s taxable and NIable pay without changing the gross pay. Attached screenshots show the setup. Due to the unique requirements I have created an Information Element, called ‘NWINF PENP Taxable Benefit’ and a custom Balance, called ‘PENP Taxable Benefit’, for the first time. The payroll calculations are working correctly but the results are not feeding in to the PPAR or payslip.

I think this is to do with the Balance Dimensions but I’m struggling to find clear guidance on what should be selected here so I have copied these from another Balance but this doesn't seem to have worked.
