Man,
I’ll try to give a simplified example;
Up to yesterday when I wrote a simple automaton pass (volume) on my many group tracks, it did not create an additional volume date lane. The track turned red and the pass was recorded and read back just the way I like it and wanted it.
However, the new thing is…whatever settings I’d apply : automaton panel = show none/used/used only …or in the track context menu = hide all, it only works in read mode after the pass.
Now if I touch to write a change, it brings up the automation lane yet again 
What did I do to change that behavior ?
thanx,
