Sion Bug with his passive and buffs

Hello Everyone. After many days of sion rework i played him again i see this bugs: When some one killed sion with buffs and while his passive he got his buffs back, he will get bug ( bug is: sion will have vision bug of buffs, he will look like he have buffs but he will not get the use of it, its just a useless vision of buffs). Soon i will try to show it with a pictures. Also there is a bug with Ravenous Hydra Anytime sion uses he will not show attack animation of it. I can't explain it correctly, better check it on game, and you will see whats wrong.
