Azir Auto Attack bug

So after playing well over 40 games or so I've noticed a bug with Azir where I would summon a soldier, auto attack, Q, and go for a third auto attack to prov thunderlords but the auto attack fails. I'm pretty sure I'm in range of the enemy and soldier and the enemy is inside the soldier range. This didn't bother me as much until I noticed how much damage I'm starting to lose out in lane and how many kills have gotten away. So I decided today to post about this small problem.
