BandHelper recently started adding spacing automatically when the Chords field contains a chord chart like this, where | is a bar line and - is a repeated beat:
E - - - | E - - - | E - - - | E - - -
A - - - | A - - - | E - - - | E - - -
B7 - - - | A - - - | E - - - | B7 - - -
It will automatically add an extra space after the first and last chord in the first two lines to match the longer length of the B7 chords in the third line. This keeps the bar lines lined up, making the charts easier to read.
In your case, you're using | for bar lines, but you aren't using dashes to show how many beats are in each bar, so this function is getting confused. The function doesn't run if the field doesn't contain both pipes and dashes, but it is running in your case because you have dashes in some of your headings, like "sakte - piano." In the next app version, the function won't run unless a pipe and a dash are used on the same line, and that will take care of this example.
Another way to stop the auto-spacing from running is to add any formatting in the Chords field. For example, if you apply bold to the headings, it won't run.
