Before the sync, all files appeared with the correct time in MC10. After the sync the only file that had a negative number was the one track that was not completely played.
The next time, before the sync, tracks 1,2,3 had a correct value in last played on MC10, and track 4 had a negative number. I had played tracks 5 and 6 to completion and stopped track 7 early. On this sync, all last played values were set to negative numbers, including the onese never played. The only correct one was track 6, which was the last one played.
