Touché (SE)'s mechanism is very sensitive. Therefore, even when you don't touch the controller and its touch plate is in idle position, its sensors might send some MIDI messages from time to time (mainly with a value pending between 0 and 1).
If you leave your Lié track armed upon playback, even if you don't actually hit the record button, these real-time MIDI messages might interfere with the automation you had recorded before.
To prevent this from happening, you can either un-arm the Lié track, or hinder Touché (SE) itself from sending MIDI altogether. This is quickly done by sending your Touché SE to Freeze Mode. Just press the Encoder once and Touché (SE)'s LEDs will pulsate to indicate it is frozen. You can unfreeze the unit by pressing the Encoder again.
As a side note, you will also have fewer of these random MIDI messages when you decrease the sensitivity of your device as described in this article: Adjusting the mechanism's sensitivity
