Azir gameplay

Ever since the last big update i have had a big problem with playing Azir. during my games when i am playing him, i will click on a minion or enemy champion he will him them once and start to walk to either top or bottom lane in a directed path towards a friendly minion. this problem usually starts to happen around level 6 and only happens when i am using a soldier to attack the enemy. also when i use my ultimate sometimes actually once or twice a game at least the ultimate will cast in the wrong direction. sometimes sideways and sometimes just backwards.
