Azir Ultimate Teammate Bug

I was playing as a vayne with an allied Azir on my team. We were running in the jungle from 3 enemy players and he used his ultimate behind him, setting up to send a soldier in and "e" stun them. I was behind him with he ulted and 3 things happened that were problematic. I was pushed backwards by the ult as if I was his enemy, he was unable to dash across the wall, and the 3 enemies following us were able to walk through the wall (or in Nidalee's case jump over it). Basically, to sum it up, A friendly Azir's ult was reversed, acting as if it had been case by an enemy azir affecting us, and not affecting the enemy team.
