After lengthy checking, (thanks amal) I came to the conclusion that i or the app messed up. Weird behaviour I am experiencing that make no sense at all. Maybe I should have bought from dangerous things, as the supplier from my chip is not very fast in replying. (even after having seen my message)
I am not able to use an app anymore to change the password (idk why) and nfc tools started not reading more than first 2 entries.
I must repeat It could have been user error or the app, both are equally likely imho.
