Some CC Messages are ignored

Hi,

I have a strange problem that seems to be a bug, I guess:
On my Midi-controller I have a lot of pads that are configured to send Midi CC messages.
In CSS I added Pads in my Controller-template and configured them as type CC and switch-type toggle.

But some of them are not working – for example with CC value 120.
I can test that with a simple script:
I added a mapping and used Pad1 (Midi type: CC / Midi Channel = 14 / Midi Value = 122) -> everything works
Now for the same mapping I switch to Pad2 (Midi type: CC / Midi Channel = 14 / Midi Value = 120) -> the script is not working anymore

All pads are configured the same way, except the Midi-Value (Midi Type and Midi Channel stay the same)
Can someone confirm this?
