Hello

I put a song together couple weeks ago and transposed it from D to Eb and saved it. Today I want to go back to D and it wont transpose. In fact it sounds out of tune. It's like there are two sets of instruments playing - 2x bass, 2x drums etc. When I go to mute any instrument the instrument still plays. Like I've turned one off but not both. Very weird! I've unfozen the song but nothing changes, it wont transpose back to D.

Does BIAB only transpose once?
