need some help with cdj 200

So i have a couple questions about cdj 2000s

1. How come it takes so damn long to load cd wave and bpm information? when using the mk3s it was almost instant and the mk3 remembers the wave form if i eject the disc and put it back in? is there an option for this on the cdj 2000, i hit memory with usb stick in but stillit loads the waveform everytime

2. sometimes when using a usb with tracks from rekordbox the waveform is not there? theyve all been analyzed and exportted via rekordbox so I do not know whats up with that

thanks for the help team,
