How use waveform and synk on CD(MP3)?

I have CDJ-2000nxs.When i use tracks exported from recordbox to usb flash drive,the sync button is work and waveform with grid are displayed.But when i insert CD(mp3),waveform with grid and synk is no work.How i can use cd with grid waveform?Maybe its fixed in new firmware?Why main waveform is scaned  and completed ?but not displayed higher(in grid waveform)
