I'm running Band in a Box 2021 on my Mac Big Sur.

It goes pretty well, except that the sustain command no longer works on many styles.

For example, when I type G... into the chord window, it should hold a G chord for the full bar, right?

For the style Puerto Rican Alguinaldo Style._AGUINAL.STY. this doesn't happen

It just plays a single beat G chord, same as when I type G.

Attached is the chord chart I am using, and a render of the piece.

Is there anything we can do to make this style played a sustained chord?
