I just tried that with a test song, and the mute settings definitely did save and after reloading the song, the mute settings still worked.
Steps:
- Using F5, Mute Bass and Drums on beat 1 then select Back to Normal on beat 3.
- Play song.
- Save Song.
- Open a different song and play it.
- Open original song and play it, Mute settings worked as expected.

Presumably, you are using F5 the same way?
