Addled Grizzly not buffing minions created in Anomaly - Nesting mode



I was just playing dalaran heist 1st chapter in anomaly mode(nesting), which states that every minion has deathrattle summon a 1/1 copy of the said minion.
In one game I had addled grizzly on the board and NONE of the summoned 1/1s received the buff from the grizzly. The animation on the card worked, as if was buffing them, but the stats didn’t change.
