I've been running BIAB from the remote hard drive (2020 version,MAC). Just loaded 2021 BIAB onto my new MacBook Pro. Then moved "My Songs" from 2020 to 2021. Now the first few songs I have chosen from My Songs gives me the warning that the song style I was using is not available and to pick another one. How do I make sure the song styles I have in my 2020 songs transfers to the 2021 version?
