Some greek names are wrong ( I think)

[Tiberius Nero]

The only mistake in Greek I have seen in EB is about Zeus' statue in Olympia called "Zoanon" instead of "Xoanon"; well I suppose this comes from the undying habit of most native English speakers to pronounce Greek Ξ (= ks, as in accept)) as they pronounce English X (that is, like z oftentimes), when in fact usually those represent completely different sounds.

Also a few of the Greek personal names that come up look a bit bizzare at times, I am not sure if all of these are attested, but other than that everything is in perfect order.

Still quite unsure what mistakes the original poster is refering to, an example would help.

P.S. You can p.m. me in Greek with them, if you are not too comfortable with English, that is modern Greek...
