Template talk:Works by Studio Dragon

About planner or producer
Studio Dragon is the planner (기획) of Vincenzo and Navillera, why are they different in Template:Works by Studio Dragon?

I know that Navillera has a creator, so the problem comes: Why 기획 is Creator in many articles? Creator (크리에이터) is creator, planner is one of the producer titles in Korea. 기획 is the producer in Navillera but it's the creator in Vincenzo? It makes me confused.--Sa Young Sun (talk) 12:22, 14 April 2021 (UTC)
