For some reason, the citation for sex is not being imported into FTM2012. The only way I can make it import the sex is to edit the citation on my Ancestry tree by ticking the box that says 'Gender' and then synchronising the trees. It is a pain to have to do this every time.
If I just add the censuses on my Ancestry tree and then synch from FTM, every person on my tree in FTM, in Person View, shows three zeroes against the sex.
I'm sorry if I'm not explaining very well.
