Cyclone build bugs Aul's fight

I noticed that, when trying to kill Aul the Crystal King with my Cyclone Champion, whenever Aul uses the "Otemba!" Shield Charge attack (including the first time in the fight), instead of aiming the projectiles at my character, he seems to fire them all around the arena, hitting the cocoons and immediately triggering the bullet hell phase. This happens even if I stop spinning before he shouts "Otemba!".

Whenever I try the same fight with a non-Cyclone character, he seems to behave properly. I also tried spinning in place without moving the character around, but it stills seems that it triggers Aul's erratic behavior.
