I used generic awakening gem on Kate Bishop and took her to sig 30.

Her awakened ability description says that her Dialed In passive increses by 1 and also subsequently increses by 1 for every 100 sig lvl.
But I am only able to get 2 stacks of 'Dialed in' passive which is same as her unawakened version. I should be able to get 3 Dialed in passive on awakening right? Is this a bug or am I wrong in understanding her awakened ability?
