I took a look on my phone and there is no "right list", but maybe this helps. When you have a list of songs to play, don't tap, instead press and hold on the first song and a popup menu will appear. Tap the one that has an arrow pointing right and three lines below it. That should play the songs in your list.
Or just get rid of the Lumin app. Before I got Roon I switched to BubbleUpNP. The full version (you need to buy the BubbleUPnP UPnP/DLNA License) is 5 bucks. Best money you'll ever spend.
