I believe you might be seeing implementation of a new feature called natural arrangements. From the Help file:

Natural Arrangements option has been added. If you give a pro musician, a complicated chord progression, with fancy extensions like C7b9b13 or Gm11, the musician may reinterpret these rather than playing them exactly as written. This can achieve a much better sounding arrangement because the musician has freedom to choose from similar chord extensions. Now you can get Band-in-a-Box to do the same thing; you can set this on a global basis (all songs, all tracks), song basis (current song, all tracks), or individual tracks (current song, specific track(s)).

One way to reset it is to use Control-N
