Unability to save the chords name in the palettes
1) Create new score and add chords names.
For example, with this configuration in Style -> General: MuseJazz Musical Text Font + Chords Symbols: "Jazz" Appearance and "Standard" Note spelling
2) Drag and drop these chords names (with Ctrl + Shift) in a palette, eg, Symbols palette.
Result: various. Examples: the "F" fails (nothing happens in the cell). For "Cm": only the "m" is saved etc. See image.
Same result after Save and Reload.
Note: I tried other configurations, with different "Text font" (Emmentaler eg) and other "Appearance" and "note spelling". I fail to find a consistent behaviour.
