Autoprefixer not adding prefix for IE

Question

I'm trying to use Grunt-Autoprefixer in my project but its not adding prefix for IE9 transform -ms- http://caniuse.com/#search=transform

I have IE in my browserlist array Explorer >= 8

browsers: [ "Android 2.3", "Android >= 4", "Chrome >= 20", "Firefox >= 24", "Explorer >= 8", "iOS >= 6", "Opera >= 12", "Safari >= 6" ]

yet, transform: whatever becomes

transform: whatever -webkit-transform: whatever

What am i missing?
