Perhaps due to the behaviour of the politicians more than their policies. A lot of left wing politicians and parties seem to be openly condescending to people they consider 'uninformed', whereas a lot of right wing ones will at least pretend to understand where they're coming from. Perhaps also because some people value social attitudes more than economic ones. Perhaps some people say, dislike immigration more than they dislike economic inequality. Maybe people would vote for parties with 'liberal' economic views and 'conservative' social ones, or 'conservative' economic views and 'liberal' social ones.
