So I directed "Shift+F1" to "automation - toggle write for selected tracks". It displayed the same incorrect behavior by toggling "write" for tracks 3, 6, 7, 9, 10, 14, 15, and 16 plus whichever track was actually currently selected.
This was all with plug-in version 1.0.7 and "sync project and mixer selection" was selected.
Interesting thing. If no tracks are "write" enabled and I select track 2. I then chose write enable from the AT. It write enables all of the above mentioned tracks (3, 6, 7, 9, 10, 14, 15, and 16) and track 2. If I then go to one of the other track like track 3 and toggle "write" on the AT it clears the "write" from all of the channels except track 2.
It seems like those tracks (3, 6, 7, 9, 10, 14, 15, and 16) are always selected and it cannot de-select them.
BTW, clicking "write" for a single channel on the software screen only enables or disables writing for the one channel.
