I finished correcting the grid, added cue markers and locked the BPM. Loaded another track in the same deck in Traktor, switched over to iTunes, changed the genre just for test and loaded the track in Traktor again. The track was totally reseted with wrong BPM, the grid marker at the wrong place and all of my other cue marker was gone. All that was left was the BPM lock.
