Another Kindred E Bug

So, I was playing Kindred Jungle, roamed top to gank Fiora, cast E auto twice and canceled third auto animation when -she used parry- I autoed to execute... Nothing... This happened 3 times in the same game so I decided to recreate the scenario, I know I didn't auto when she used parry so I guessed It had something to do with the auto cancelling... It was the auto cancelling...
