Current poppy bug I've been witnessing

So poppy's ult is supposed to send all enemies hit flying right? Well since the start of patch 6.6 whenever the ult connects with the first enemy, the rest of it is cancelled meaning it only sends one person flying back towards their base. This has been an on and off bug in my games, firstly in my own games and as I just witnessed in my last game where my friend tried to ult defensively to stop the enemy team from sieging. The bug resulted in his death as all other enemies were still in our base.
