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?

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.
