Aatrox Q not working properly

Hello everybody yesterday i noticed that the CC immunity granted by Aatrox's Q (dark flight) does not ignore some CC even tough a couple of patches ago it made to be so In my case i noticed that Quinn's E can displace Aatrox at any point during the execution of his Q (even the terminal part) and i've heard from other people that this isn't the only case but i'm not aware of every instance of when this happens

any fix anytime soon?
