I have to report that the track Ducker, which I use all the time in Wavelab 12, has become almost non functioning in Wavelab 13, especially the Attenuation Hold time, Music Fade out and fade in, these controls that operated smoothly in Wavelab 12 are now erratic and mostly non functioning, making this option in Wavelab 13 unusable.
I experienced a similar problem with options like this in the Wavelab cast version.
hopefully we see a resolution update fix for this, as it stands now, I have to go back to Wavelab 12 for any voice over work,
