Attack Move with Target Champions Only

So I've been experimenting with hotkeys as a way to better myself with the tools available to me, I bound my left click to auto attack move when the option was available, and now I'm trying to get in the habit of using Target Champions only as well. It appears to be bugged to not affect my left clicks. I assume this is a bug so I would like to get it fixed if possible. If it's intentional, that should change imo. Otherwise I wanted to bring it up to get it fixed.
