Azir autoattacks dont work [Gameplay]

I've noticed that when Azir autoattacks with his basic animation and then either summons a soldier or moves a soldier to that target he just auto'd he will have both his auto animation and the soldier animation but no damage from either.

How to replicate:

1. auto a minion/monster/champion with a basic auto
2. summon a soldier and q towards a target while you are in basic attack range
3. there is some odd timing with it but it has happened a bit common and he uses his autoattack animation and his soldier to hit and neither damage is applied.

The frequency is not extremely high but i have seen this happen in games as Azir and vs. Azir. I tried it in a custom and it happened roughly 5 out of the 12 times.
