A stat decreasing animation plays while fighting Audrey

[Former user]

while fighting Audrey in whirl islands, the stat reduction animation plays whenever you switch pokemon even though that it doesn't state any stats decreased nor does it show any decreased stat in the stat-change overlay.

Were any of your Pokemon holding seals, were shinies, or anything that might play a send out animation? Cannot seem to replicate.
