Aatrox Sated Devourer [GAMEPLAY]

After playing multiple games as Aatrox jungle I have begun to notice a pattern. Once Aatrox gets his sated devourer he no longer gets the ability of his w passive damage or heal. I am unable to determine if they actually do not proc or if it is just that the hotbar is not showing they are going off. I would understand not having the devourer ghost proc the attack with him but to completely negate one of his abilities is a really big damage and sustain loss. The bug is easy to reproduce. Just build a devourer and get it to become sated.
