Yeah, the issue wasn't Jaune's lack of knowledge about his semblance but rather his lack of knowledge about Aura itself, which is literally the thing that keeps Huntsmen alive.

A Semblance is treated sorta like "It's fine, you'll find it one day, just keep looking." You don't need a Semblance to fight Grimm and some Semblances aren't even useful for fighting (see Jaune's Semblance, which is useful for supporting people, not actively fighting himself). Whereas Aura is literally the lifeblood of the Huntsman profession; without your Aura unlocked you are extremely likely to die in a fight, even against a Beowolf.
