"Hide Status Bar - ON OFF" holding its setting??

A

AC Question

I am not this andriod thing and am using Android 4.2.2 (Thats all it says on the box under OS)

When I go to change the setting for Hide Status Bar to OFF (I like having it show at the bottom of the screen) It will stay there all fine, I can open and close programs for the most part with no problem, but it seem for some reason that the setting will change itself back to "ON" not sure why, I can be watching Netflix and then close out only to find the Status bar gone and the setting changed back to "ON" or if I exit out of XBMC same thing, or close out for search the web. I can't really pin point any one thing. But am I right in assuming that once I change it to "OFF" it shouldn't change itself, right? Is there a Apply button I need to press or a Save after changing it, I am not seeing.
