Chord symbols playing back on only the first flow

I suspect there is a straightforward solution to my quandary but have searched and found no answer in the videos or forum. I cut and pasted the different parts of a song melody into 4 flows and want to input chord symbols to help with writing the piano accompaniment. The vocal part plays back on all flows but chord playback works only on the first flow, even though the instrumentation is the same throughout (voice plus piano) and voice and piano are checked in Play mode for each flow and the chord symbol playback button in Play mode is highlighted for all flows. I must be missing something but have no idea what it is - any suggestions will be appreciated.
