Same problem!!!!
used Midi Control Center, Stored setting, Sync'd to board.
Close midi control center, open Ableton Live, plug sustain pedal in and value immediately goes to 127.
Was able to fix after opening Ableton.
Hit EDIT, RECALL, select the bank you saved the reversed sustain pedal to, and it works now. Apparently the board doesn't necessarily remember with preset it was on last time...
