Default Android soft-buttons spacing

Not sure if this is the correct forum or not, so apologies in advance if it is not.

I recently got a Samsung Galaxy Note 10.1 2014 edition. I've also been using Nexus phones for the last few years, and therefore I'm very accustomed to the Android software buttons. I've turned them on on the tablet using
in the build.prop and it has worked great. However, I just updated to Kitkat, and for some reason the buttons are now spaced out to fit the entire width of the screen. ie. the back button is right up against the left, and recent apps right up against the right. Is there a way to change this?
