If you add commands to the playlist, use the Playlist->Add command feature, and if you modify playlist manually using text editor, include
.command after the actual command, e.g.
set autointro off.command
You can reset the playcount:

Thank you, it looks like track metadata is indeed wrong.
Currently it's a limitation, only one track can be dragged. If you need to move multiple tracks it could be better to use Cut/Paste features.
