Grandmaster bug

LPH_337

So i was putting another clear through the grandmaster today and I noticed that during his second phase when you're supposed to apply a damage effect that every time I did it, it wouldn't trigger so the timer would expire and i would gain a blunder. I had magneto (red), claire, and doom with me and i was able to apply bleeds and shocks and such however it just wouldn't trigger for the grandmaster objective of applying a damage effect. This happened 100% of the time across multiple fights throughout the phase. Has anyone else had this issue?
