The information about me in the system is incorrect. Can it be changed?

In the event of an incorrect notification, ask the employer (client) that entered the notification to change it. If the employer (client) refuses, you can submit a justified request to the ministry of Social Affairs and Employment to have your data changed. See also the ministry of Social Affairs and Employment’s privacy statement. If the employer (client) does not change the notification following a justified request to do so, the Netherlands Labour Authority may fine them.
