Kalisa's Crescendo Cursed Ground and Pacified bug

Kalisa's Crescendo with Cursed Ground, when a mob exits the curse and triggers the Pacified effect, on top of blocking Pacified effect it also blocks the effects of the curse when they enter another Cursed Ground.

i.e Elemental Weakness -106% and dropping 2 Cursed Ground, exit 1 Cursed Ground into 2nd, Elemental Weakness becomes 0% until the 8s later

Not sure if this is intended or a bug but wording of Kalisa's Crescendo sounds like it should only block subsequent Pacified and not the Curse effect as well
