It is confusing. I am also not sure exactly what happened. But I don't think that your wallet is hacked. Perhaps you changed some of the settings, or the software got corrupted. But to confirm everything, have you written to Ledger wallet support (
hello@ledger.fr, please correct me if I am wrong)?
Yes, I reported it to Ledger wallet support. The email confirmation that they received my concern said 1-3 weeks for response. I can't think of any purpose for Ledger to have a setting that would do what was described above. Sorry if situation isn't clear, don't know how else to explain it.
