darius is still w is till bugged

So i was using Dunkmaster Darius in ranked, and noticed that after i used my w his attack range glitch. His attack range gets reduced to the point it would only hit right on top of the enemy unit. And since darius can't ignore unit collision his auto pathing freaks out. Though for some reason when u left click a target his auto attack range goes back to normal, and stays that way until the next w. Not sure if this is exclusive to just Dunkmaster or it affects his other skins.
