Which track are you entering the notation on?
If this is a RealTrack (green), then it will be overwritten when you generate the song.
The Melody and Soloist tracks are usually reserved for entering user notation.
You can freeze the track, by pressing the small asterisk character next to the track name. If frozen, the notation should not be affected by changing the Style.
