Smite kills GA???

Today when i was playing zed, i bought GA. But when i was almost killed by Azir, Shaco appears and smited and killed me. But i was really surprised when my GA did not work. I am wondering if this is a bug with the new GA? The game detail is right here. http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/1638467561/200799320?tab=overview + > + :(
