What causes this issue?

Regarding the anonymity tax in the wage tax, identifying the employee
during the course of the year will have no effect on the wage tax rate
(52%) already applied to previous payments. In principle, this field can
therefore not be changed retroactively.
Regarding national employee insurance contributions, it is possible to
alter the tax-free allowance and maximisation retroactively. However,
the Special Employee Groups code cannot. The calculations used according
to the Basic Method for Calculating Growth always ensures that, in the
current payroll period, it is automatically adjusted for the entire
year.
