CC7 Data in piano roll not corresponding with Kontakt

Hi there,
I have a little bit of a problem with my CC7 “Main Volume” data. Whenever I put in max. values manually in the piano roll, it will only translate to about 50% loudness in the Kontakt Fader

Hope the picture illustrates the problem. Does anyone have an idea how to fix that?
Cheers
Nicolas

For whatever reason, NI makes it work like that.

I just assign a different CC to the volume slider using midi learn and I get the full range.
