main volume control inaccessible

I glued all takes within a track together, but still I cannot grab it to remove, probably within some other track, and that’s another problem I’ve been having, creating tracks with distinct midi outputs. Any idea why is this?

Nothing changes it? Not even the pen tool?

The problem was solved when I hit the green automation button for the track off
