Logic 10.7.4 and Control Surfaces (MCU Pro)

Since a few versions of Logic I've had a problem with TRACK SELECT with control surfaces. If I press the Track Select button on my Mackie MCU Pro, the correct track is selected in Logic, but the first audio plugin that is in the audio FX slot of the respective track is also started automatically. The first plugin that is in the slot is always displayed as a window. This symptom also occurs with other surfaces such as the Softube Console 1. If I select the track in Logic via the mixer with the mouse, the respective plugin window does not open. I could despair. I've checked all logic parameters that are likely to cause this behavior.
