[GAMEPLAY] Azir cannot attack inhibitor while it is in a soldier's attack radius

Recently, I've been playing Azir a lot, and every time I drop a soldier near an enemy inhibitor and attempt to auto attack the inhibitor, it doesn't do any damage to the inhibitor. I'm aware that soldiers cannot attack structures however, Azir runs through the animation of commanding his soldier to attack the selected target but the soldier does not run through the animation nor does it deal any damage to the inhibitor so long as the soldier remains within striking distance of the inhibitor. There is also the sound of one of Azir's soldiers attacking a target but it doesn't match with the animation.
