In the in-game news it's a little bit clearer, because it's written like this:

O [Determined Defender] Goku

X [Innocent Challenger] Goku (Youth)

X [Supreme Warrior Awakened] Super Saiyan Goku

So I blame dbz.space! Although they do mention the "second names" (which, I suppose, are "Determined Defender", "Innocent Challenger"...) which is pointless and just makes it more confusing.
