two bugs ingame

first bug is when kata is playing vs a yasuo and his 3rd Q. so everytime i dodge a yasuos Q by jumping with my E either on a minion behind him or on him his Q always hits me even if i clearly saw that it didnt and knocks me up after my E animation is done. but this game i played i pressed E and R and somehow my champ kat did E then got knocked up for a brief second and then R from nowhere. so i got an ult wasted and no E and yasuo just killed me. please fix this katas E its annoying how the cast time is countered by everything and then bugs appear. second bug is the quick cast with indicator. i always buy hextech gunblade but i always end up pressing 2 around 6-7 times before it activates the item. fix this too
