Yeah Rebirth, and not just in Wonder Woman is something of a huge mess of continuity. Diana might have one of the worst cases admittedly since it certainly seems to be contradicting the almost immediate Rucka run.
But I think it's best to just think that continuity is quite literally is being written and re-written during Rebirth and has no set position at the moment. It's what I've worked on the assumption of, especially because of the continuity fest of the Justice League of America book which features stuff and characters referencing stories that CAN'T work as they do with current continuity.
