So it shows the apps you've restricted background data access for at the top of the list. That's all. Maybe the software designers thought that for some reason it was important to let you know which apps you had restricted background access for? Personally I'd think it more important to warn you which ones you haven't restricted, but I don't have Google's mindset

But if you know that Game Booster (a name that would have me looking for the uninstall or disable buttons, as all "booster" apps are invariably junk) has only used 10kB you now know how to check their data usage, and if you don't use these apps much it's no surprise that they aren't using much. So I don't see any problem here myself.
