No Midi-signal from Cutoff and Attack

[Motion Drive]

Playing around with my NL4 since a few days, i recognized some strange behaviors.

Somehow i can't record any midi-automation with the Cutoff and the Amp-Envelope Attack on Cubase 7.

With all the other knobs, the automation is recorded perfectly.

Strange thing is...on the Transport Panel shows that there's a Midi Signal entering but nothing is going out.

With all the other knobs...theres a in and out signal on the transport panel.

Any inputs anyone?
