Anyone else found this? When adding audio keyframes - mainly fades in/out - to a Multicam sequence, click the "add key" button to add the first key at 0db, move the playhead, then drag the Level down to -∞. This should create another keyframe at the new time at minus infinity, but it doesn't - it creates another one at 0. To silence the audio you have to drag the "value" rubberband (under the keyframes) down. This doesn't happen with other properties, eg opacity. Seems like a bug?
