There are plenty of times when you’d want to block the channel fader from recall without blocking your send levels, it wouldn’t be viable at all to have them lumped together. Mixing IEMs from FOH would be one obvious example. The musicians want their ear mixes to be exactly the same as when the scenes were stored for each song, but the FOH mix is being actively mixed depending on how it sounds in the room at the time and you don’t want your faders resetting each time you recall a scene.
“level” in this case means “channel fader”, maybe it could be renamed?
