Dragon Ball: Curse of the blood rubies (Frontier Enterprises dub 1986)

An unknown fifth (chronologically first) dub of the movie may have been done by the Tokyo dubbing company Frontier Enterprises. This is based on comments made by Frontier voice actor Richard Nieskens, who had previously listed it on his linkedin profile (albeit he erroneously refers to it as Dragon Ball Z). Given his comments in an interview where he states it was done around 1986, and given Frontier's dubbing activities at the time, that likely means it was the first movie.
