Default Missing apps.

Hey guys.
I recently noticed a strange thing on my One VX. There are a lot of apps installed the phone that don't show up in the app drawer, for example, voice recorder, mirror, Polaris office, etc. But when I look in the installed apps list, I find them there.
Are you guys noticing this too on your phones or am I the only one?
