I don’t know if this will be fixed but I just want to mention that I found somewhat of a work around at least when tying this parameter to an animation. If you create an animation with 30 frames you can then render blank frames in specific spots to account for the skipping around that’s going on here. Basically there are 30 filter shapes so if you create blank frames to account for the filter shapes that are not available for the waldorf type then you can sync the movement of the parameter with an animation properly.
