internal door button lights - 2013 OB

My car is relatively new so Im not sure if this is a problem or just how it is.

My door buttons on the front doors light up a red color - but 2 of them dont light. On the drivers side, the window lock button doesnt light - but all the rest do (door unlock/lock, and window open buttons). On the passenger side, there are only 2 buttons, one for the window - which lights, and then theres the door lock/unlock button - that one DOESNT light.

Should they ALL be lit?
