Achievements bugged for Vergil?

[10Tickles]

So apparently the only achievements that can unlock while playing as Vergil are the ones specifically tied to him. I just beat all his missions with an S rank on human and did not get "Let's Rock" or "Hell of a Hunter."

I also didn't receive "Battle for the Ages" and "Obedience Training" doesn't seem to want to unlock even though I made the boss skip the lightning phase and go straight to ice after fire.

Rather annoying to get stiffed like this, as I guess I'll have to replay the entire Human campaign and get all S ranks again as I doubt it'll count towards "Worthy of Legend" if it didn't for the rest.
