The sequencer mode "Round" only works when you're in Pattern mode, not in song mode. Other sequencer modes work do work however.
I can see the point that "Round" mode is different from the others in that it works across 32 steps, not 16, but is that a reason for it not to work in song mode?
I've got a really nice up-up-up-up-down-down-down-down arpeggio going which is ruined by this
