Are you referring to her Rush (Finnegans Wake) or Multi (Rain of Arrows) skill? This just means that it hasn't awakened yet, which can only be done in quests.

I'd suggest using her in Burst whenever you get the chance, Dice if it's her Rush that isn't awakened yet, or Flail if Multi's the unawakened skill, and it will usually awaken pretty quickly at 1000 loyalty. Make sure that you're either doing this in the current event quests or storyline quests, though, since skills cannot be awakened elsewhere.
