default led behavior with virtual dj le (rmx2)

hi all, stupid question: i bought a rmx2, installare on my macbook pro. all work fine. i need only a confirmation. is it normal that when i launch vdj le on my mac, and when it is completely loaded, in the rmx2 before that i touch anything in it there is the button left arrow (numeber 8) lighed and also the cue left button lighed?
thanks
mike
