Benefit amounts are wrong on T4 and RL-1 when generating T4 and RL-1

Method 1: Manual Adjustment

1. Create a paycheque.
2. Date it in required payroll year and replace the cheque number with "Adj" or similar. 
3. Remove all preloaded amounts. Make it a $0 paycheque.
4. Enter the missing amount into the proper user-defined benefit fields.
5. Put in $0.01 in Vacation earned field on the Vacation tab.
6. Post the transaction if it shows $0 for cheque amount.

Method 2: Void and Repost All Affected Transactions using updated Sage 50

1. Lookup the affected transactions.
2. Note all pertinent details.
3. Void the transaction.
4. Enter the paycheque anew with the same initial values.
5. Ensure the Gross and Net amounts are the same.
6. Post the paycheque.

When I consult or adjust a paycheque, the customised Benefits, Benefits Qc or Reimbursement do not appear on the screen.
