Beat all Zodiacs, still no acheivment!

[A BROUHAHA]

I've beatent all 12 zodiacs, (counted through all of the emblems you get for beating them, they are all there), and I still have gotten no acheivement. I was under the impression there was an acheivement for doing such on xbox360, am I mistaken or did I do something wrong?

There's 13 because there are 2 Gemini.
