Welcome back to the Wefugees community and thank you for reaching out to us.
If this mistake causes so many troubles for you, I would recommend you to explain to the Ausländerbehörde and ask them to change it. They also have an interest in your correct data and identity.
I don’t think you being transparent produces a bigger risk for deportation in this case and that they might not issue a new Duldung.
Would you agree @mbeon-Bernd or @mbe-on_Zsigó?
Please don’t hesitate to get back to us with any further questions.
All the best,
