Curve Deformations

I’m trying to try out the new curve deformation tool in 2.35. I’m having a big proglem though. I have a double helix ribbon that runs vertically, when I parent it to the curve, it follows the curve but is flattened. Its like I pressed my helix in a book, then layed it along the path. Any hints on how to fix this. I’ve also had this problem before when extruding along a path and never could work it out.

This question was just recently asked:
It appears to be a tracking problem.
