Morphed pencil lines losing curvature

I’ve been having an issue with morphed pencil lines in Animate Pro 3 for OSX. For what it’s worth, I did notice this problem in 2 as well.

I’ve attached an image. What’s happening is that some of the lines between points are straightening once the morph is applied, despite smooth curves on the lines prior to the effect being added.

The interesting thing is that if I look at the line’s contour with the contour editor, it’s still correct. It’s just that the morph seems to have simplified the final curve information. A render looks the same way.

Has anyone else encountered this and come up with a fix?
