Customising track order in playlists

[Themeth]

Hi,a problem has arisen with the melco app update 1.19(1.19.05). it concerns customing the track order in playlists. Editing a playlist by scrolling tracks into the reqd order and selecting 'Done' completes the new order as before. However the new order is not retained when retrieving the playlist following leaving it. I note a new icon for set options for track ordering- has this compromised customising?. NB I have just become aware that sometimes the desired track does not stay in position during editing but returns to its original position immediately? Very strange, am I missing something?[/size][/font]
