Yeah, much like Palpatine was once referred to as "Senate President" rather than Supreme Chancellor in books published prior to the launch of the Prequel Trilogy and firmly establishing terminology from that period in history. Same office, just a different title.
It's the same planet, just with a change to the spelling. They even sound almost the same so it's not like, say, the decision to alter the planned name of the Klingon Homeworld in Trek from "Kling" to "Qo'noS." A lot more obvious a change.
