Can you describe exactly how and where this is happening?
-- Google Preview arising from a search?
-- searching on a desktop or on a mobile device?
-- ordinary search or a mobile app?
There are currently THREE separate Googlebot-Mobiles, all with recognizable UAs such as "iPhone". So they've certainly got no excuse for not being able to find the mobile version of a site.
Feature detection is one of the big failings of Preview. It shows what the googlebot-- of some kind-- would see, not necessarily what the human user would see.
And when you're done, come back and tell us what your native language is. I sometimes see g### called "he", but can't remember seeing "she" before. Unless the implication is that G, like Mother Nature, is a you-know-what.
