This is with Emplode 2.0 Final.

While I was away for the weekend, I used the remote to "mark for attention" several tracks on the player. When I got home, I did the various things I needed to do for each track, which was a combination of copying tracks to a different playlist, deleting songs and/or playlists, and in one case, marking an album playlist as "ignore as child".

After each time I did these things, I went into the properties of that track and unchecked the "Marked for Attention" checkbox, hit OK, and then synched.

Of the tracks that I didn't delete, all got unmarked except the last one. And I have tried to unmark it and synch twice more, and each time it still comes up as Marked in emplode after the synch is done.
