Reply to CDJ's with timecode and Traktor, problems cueing tracks

A friend of mine has just bought the Audio 10 to use with Traktor and his cdj's. He's having problems where as when he has a cue point stored on the tracks in the software when he presses CUE on his cdj's it doesn't CUE the song. I seem to remember having a similar problem when i used cdj's with the audio 8, i cant be sure but believe i may have had to press the track back button on the cdj then the cue button for it to cue up at the start on the cue point. Does anyone know if this is normal, anyone have/had the same problem, how do you sort it/fix it??
