Key transpositions and player settings made to a chart opened From a playlist,
Stay with that chart.

Any changes to a chart made using the editor (no matter how small)actually overwrite the original and create a new version that’s different from the original and, as you discovered, that change happenseverywhere.

If you want to keep the original unchanged, you must choose EDIT > DUPLICATE.
This creates a new, separate version of the titled song. (With a newly added number)
I often change the number to a descriptor (initials) so I’ll know what’s what
(Example All of Me RB1) (or band or singers name or initials) etc.
Add it to the playlist(s), remove the other version
CAUTION…two choices… remove (but keep in your library) or TRASH which will make it vanish from your app and playlists…..choose carefully.
