Roku 3 - Large playlists

[j808]

I have a playlists which includes 1,602 songs - when I try and scroll to view these songs on my Roku 3 it only scrolls a certain way before it stops.  Why can't I view the entire playlist?  Also,  I usually listen to this playlist on Shuffle mode but I have a feeling it is not including all songs when I listen. 😞
