Control Issues with Morde Ghosts

Was playing 2 games, both games I noticed my dragon ghosts would listen to walk commands but kind of attack whoever they wanted. Didn't really think anything of it until I was 1v1 against a and I had a ghost with me. Could not make the ghost attack him, was pressing R key and Alt+Click but nothing, it was just farming some nearby minions. Said something about it to my team and my mid laner just bashed me for it, idk why I would lie about it, I didnt lose the duel or anything...

So to sum up the bug I experienced, seems like you can make the ghost walk where you want it to but it wont attack who you tell it to.
