Darkseid and Highfather

Justice League #23.1, I mean Darkseid #1, was released a couple of weeks ago. Don't get me started about how much majesty Jack Kirby brought to Darkseid  and Highfather when he wrote and drew those characters. Instead let's just talk about proofreading.

Highfather's given name appears three times in this New 52 issue. The first time it appears as Izaya, just as Mr. Kirby always wrote it, but the other two times it appears as Ixaya. Huh? So which is it?
