Kayali Vanilla Rock Sugar 42

My sister has a bottle or this, bought 1,5 years ago. I lately bought a travel size and it smells completely different than hers. Mine smells mostly like Vanilla 28, this boozy vanilla, spicy etc. But hers smells like it is described to smell like.. and the difference is there already when smelling it from the bottle, not only on skin. Why this could be? I am dissapointed as I expected it to smell like the one she has.
