More CV Expander?

[Slim]

So I mean:
I use a CV expander track.
I have nothing on that track. I insert notes (pitches). When I play the sequencer, the entire column is switched to automator (and the pitches do not play).

If I go to the column again and I delete the automator, it works temporarily (i.e. the automator behavior is indeed deleted) but when the sequencer runs, the entire column switches back to automator mode by itself (and I don't know why).
