MY Adri doesn't work Witch's Remnats in Dragon

[frail swan]

She's not attacking the center dragon. She's attacking its second head over there on the left (The tail). Because of that, the debuff is going on the tail, where it won't be shown.

Notice how there's 3 lights? Those three lights are each a target. Only the center target's status will show.
