Hi Ente35,
Thanks for reaching out.
I now checked 8 players. Of these, 7 already had the correct date of birth in the DB and the 8th was not existing at all.
As example: Max Fleer has his birthdate updated on 28 Jan 2023 so maybe you are checking and outdated FM22 database.
Please check your information again (with most recent FM24 DB) and send us an updated list if you can.
Thank you very much.
