Camille Ult Bugs in Poro King

So I was playing the new champion, Camille in Poro King and I used my ultimate on an Orianna, they had the Poro King up and while she was in my force field, she tapped F to teleport to it, when she did this she became untargetable inside my ultimate, I couldn't attack her nor could my team. Also when I used my ultimate on a Shaco, he ulted while in the force field and it completely canceled my ult, like the force field disappeared when he ulted. If yall could look into this I would appreciate it.
