You must use the "set" method to update an entry. (Again)

Hehehe I think that would have been an alternative way but I could found the reason why it hasn't worked. I was able to backtrace loosing my data inside the doProtectFields method. I vardumped the information from the allowedFields and then there it is right in front of me the whole time also posted here, the error

PHP Code:

protected $allowedFields = ['role_id, first_name, last_name, username, password, '
    . 'email_address, mail_me, ack_round, language, referee, xp, uuid, '
    . 'activation_token, activation, dsgvo, notified']; 


Maybe you can see him also Thx for your help
