LOOPS AND CUE POINTS NOT SAVING

I'VE BEEN NOTICING THAT ALL OF MY LOOPS AND CUE POINTS NOT SAVING.  AFTER JUST SETTING AND SAVING SOME CUES AND LOOP POINTS ON MY XDJ-RX CONTROLLER USING MEMORY, I REMOVED THE USB STICKS TO UPLOAD SOME MORE TRACKS IN REKORDBOX AND NOTICED THAT THE LOOPS AND CUE POINTS I'D JUST SET ARE NOT THERE.  AND THEY WERE TIME CONSUMING TO SET IN THE FIRST PLACE.  FRUSTRATING.
