Achievement Aficiando unattainable on steam?

The achievement Aficiando (Halo 3: Complete three Halo 3 playlists), does not seem to be able to be attainable on steam, since after i completed the requirements i unlocked it on Xbox but not steam. There are other achievements have the same problem, for example people have said they the “have all according to plan” achievement on Xbox but not on steam. The achievement is also unlocked in game. Will there be a fix to this?
