Q Light Controller+

hi,
is it normal that when I assign a channel loopback there is always a question mark in the input channel?
I get the same question mark when I forget to assign an input profile to a midi controller.
Btw it's working, I'd like to understand if it's only a "default" channel message or I'm missing something.
Here a picture, thanks in advance for any "feedback" :)

it means there's no input profile assigned and therefore channels do not have a name.
It's normal.
