HI Carl; There are many pieces of music in the Baroque, Classic and Romantic periods where the same block of music is repeated without an alternative.
This particular example is a simplified version/arrangement of a Chopin Waltz. The problem goes away when I disabled the forced line breaks, so I do think that there is a problem here, although it is an annoyance, not severe. There is no problem with the bar checks after I disable the forced line breaks.
