I don't know much about Italy, but the leaked Panko name is odd.
Olivia isn't used as a surname there, from what I could find, but the leaker put it in as if it were hers.
If italians names work like spanish names do, it's likely that those are actually her two forenames, so they didn't post any of her last names.
My theory is that the leaker copypasted the name from a database, didn't check if they actually copied a last name and didn't do any investigation themselves, since I could find that mistake so easily.
Also Olivia IS used as a surname in SEA, so the leaker could be from there, thinking its also used like that in Italy, but I'm not sure
