If you don't play 3 gender specific matches from eligible leagues, but play enough mixed matches, you can get a mixed-exclusive rating, but I believe when you have a gender specific rating from the prior year, that still carries over instead and seems to be what happened with you.
Thank you. I did notice that one of my teammates got a new 2012 "mixed exclusive" rating at the same level he was before.
