Line 6 M9 receives Midi CC messages from Ableton from ALL midi-channels

Guys, who used Line 6 M9 and Ableton, tell me, please. Some kind of magic happens and something is wrong :) 

Line 6 M9 for some reason receives Midi CC messages from Ableton from ALL midi-channels, regardless of what channel is installed on it. With Program Change, everything is in order - it takes only from the required channel.
This happens only if "Midi Sync Out" is on (to receive midi clock). If you turn it off, then everything is OK.

With the rest of the pedals - everything is as it should. What could be the problem, and how to cure it? Thanks, and sorry for my English : )
