I've noticed a problem with BIAB. I have 32 measures of chords that I want repeated and then another 32 measures I want to move to and repeat. I enter the 64 measures then highlight the first 32, select Edit->Song Form->Repeats/Codas/1st-2ndEnding. Then select Repeats radio button, and Okay-Make Repeat button. Then I repeat for the last 32 measures. This all works great!

If I save this then use the display to enter new chords for the 64 measures and save as a different name, it works for the first time but then plays the old set of chords on the repeat.
I'm essentially using the first file as a template but BIAB is not repeating what is shown. It has somehow stored the old chords and uses them as a repeat.

Should I be doing this in a different way or is this a bug?
