Repro: (Win10)
Create a track with an expression map
Disable the track
Open it in Key editor
Inspector Shows
Enable track
Inspector still shows “no expression map” - though the expression map plays
Close and reopen the key editor the issue is resolved.
Note: This issue sometimes does not occur with ‘freshly’ created tracks, more whith tracks you return to after other work - use an old project where you have disabled track to repro
