Shown as playing Crosshair X

[KitKat]

I dont understand why Crosshair X shows up as the game i play and also that it collect game time hours as recently played. Even in private mode the game still gets shown in some mannors to others. I read you guys say you dont want people to pirate it and there for it will always be shows as a played game on steam since you dont want a copy outside of steam.
But applications like wallpaper engien also runs via steam yet has no issues being invisible to others. Not once has it showed me playing wallpaper engien or recent time played wallpaper engien. Why is that? Is this something you guys are working on?
