Andrew- When I use the new bar based section letter option (BIAB 2015 MAC build 103) it works fine, but then it "magically" inserts random bar based letters later in the song where I don't want them. And I cannot remove them by clicking "remove." There are several of these and they have screwed up my chord sheet so badly that I have trouble figuring out where I am in the song. Am I doing something wrong?
