The ability "Panacea" doesn't remove poison, it always misses

[Gianluca90]

I was in the battle with Ralvurahva, Steiner got it by Devil's Kiss and got poisoned.
When i cast the ability "Panacea" with Garnet, it always misses, and the status isn't removed.
I tried every battle mode (normal, fast, turn and dynamic) and even changed Garnet weapon (rod and racket), but i always missed.
The item "Antidote", on the other end, worked.

EDIT: So, apparently the culprit is "Beatrix only" mod. I turned it off and re-tried the battle, and without that mod the ability "Panacea" works as intended. I'll tag @Tirlititi since he's the creator of the "Beatrix only" mod.

EDIT 2: Another thing i forgot to mention is that with the "Beatrix only" mod on, not only "Panacea" skill always misses, but also the cursor DOES NOT position itself on the character with the poison status; while with "Beatrix only" mod off, "Panacea" works as intended and the cursor DOES position itself on the character with the poison status.
