track stays RED like rec automation. why ?

i just recorded a mute automation on 3 grouped tracks.
now i see the automation but the track stays red as it would be recording an automation. :cry: why is that ?
i try to remove Read, write… nothing works.
close open automation lane… same./
… oh and undo does not work anymore :unamused:
