I'm trying to create a song which has a shot/break in a bar for the first and last chorus, but not the middle. I've entered the chord in the relevant bar as "Gm7.." and when I play the song I get the break as expected on every chorus.

Then I've changed the song settings and unticked the box "Allow rests in middle chorus". Now when I play the song I get the break in the first and last chorus, but in the middle chorus only the drums play. How can I get the other instruments to play?

The song is only 3 choruses long and I am using the style _GJBALDR.STY, which uses real tracks. I'm using BIAB 2016, latest build.

I'm sure this used to work, what am I doing wrong?

Thanks for any help
