Anybody else have this problem?
Specifically, when I'm trying to map a devices on/off function in Ableton to a CC value.
When I adjust the CC value in midi mapping, the CC parameters just disappear and freeze as their default.

This happens in Ableton 9 and 10.

I used to know the fix for it when it popped up, it was a pretty easy solution, but I've now forgotten it
