I have Finale v25 on Mac, and it was acting normally. I had staccatos in my piece and their playback was fine. I added another measure, and put staccatos over those notes, and then suddenly the playback for the notes with staccatos is so quiet you can't hear them. I even opened a new file and added notes with staccato and the same issue persisted, so it's not a file issue. I don't know what I did but if somebody knows settings I could adjust, that would be greatly appreciated.
