What you can do if all else fails:

click the red "W" button at the top of the effect. This turns on "write mode".

Play a little bit of your track, and wiggle whichever parameter you want to automate.

Press stop, and then click on the green "R" button. This turns on "read mode". You can now click off the "W" button.

In your main arrangement page, right click on any channel and select "show used automation for all tracks".

The automation data you just entered in realtime should come up, and you can edit it to your heart's content.
