Hi there and welcome to the BBS!

It sounds as though you are selecting a single track and that track is being played.
This is normal operation.
If you want the entire playlist to be played, you must select the 'arrow' (first option when entering a playlist folder).
Then the playlist will play all songs.
The shuffle option must be off in order to get 'first to last' play order.
Have fun!
