Problem
The reports "Payslip", "Journal" and "General ledger" only show the employee part of the premiums (OAV, AVBZ, BVZ) and not the employers allowance and total premium.
Cause
At "Company info & Options" you selected at "Payslip" the option to "Only print employee premiums on payslip".
The "Journal" and "General ledger" show the the same data as the payslips.
Solution
1) Change at "Company info & Options" the option back to "Print premiums + Allowance on payslip (Recommended)".
2) Process the period again for the changes to take affect.
