Tracks in queue stop 1sec before ending

ISP Modem/router>NucleusPlus >Seagate 8TB HD>LINN SELECTDSM >McIntosh C452 >Mc2700>Ipad Gen7 Remote
Suddenly today while playing a self made Playlist the tracks in the cue won’t go to next track unless I do it manually. On occasion if track is in same format as next it will crossfade as it should.
Suggestions TIA
