Olivia's passive doesn't work with "Avacyn's Judgment"

Iworb

I called Olivia and https://beta.mtgpq.info/cards/AvacynsJudgment was my last card in the hand. But instead of destroy it, previous card was destroyed. It happend 3 times and I sure that Olivia's passive ignore this card. Is there a reason why it happening?
