Syndra knocking her spheres backwards with her e

I was playing an Aram when I first encountered this. I had placed down the sphere and E'd like normal except the ball fly towards me instead. Clearly this could cause big issues with her gameplay as that doesn't seem like it is working as intended. It seems to do that if you place the sphere down and e as soon as the opening would be there. When it spawned in on the wave it shot backwards. If I would do it just a little later in the spheres creation it would work as intended. Also quality is low on video. And the audio issues that come from highlights are in the video as well.
