Alternate Appearance Pack 1 un-purchased

I purchased every single DLC for Mass Effect 2.

Today I found that the Alternate Appearance Pack 1 is showing "Buy Now" and it's dated March 2010.

Now I can't remember exactly if I purchase this DLC in particular but I do remember buying ALL that was available this year.

So either this DLC was not in the list when I made my purchases or I'm robbed of a DLC.

Can someone explain?
