Apple Music Playlist on Roku Will Not Play In Order or Remain Within Playlist

I have the Apple Music App on a Roku Ultra that is fully up to date. When I start a playlist, the playlist will no longer play in order, it acts like it is in shuffle, even though shuffle is not selected. Worse, though, is that before the playlist has finished, it will start auto playing to similar songs outside the playlist. How do I get it to go back to just playing my playlist???
