Variable Font Contour Interpolation

Hi, I’m new with the software. Trying to create a variable font but got stuck with this contour problem.

As far as I know, I need to match each node from the Regular and Bold masters in the correct order, but I’m not sure how to reorder them.

Also, are there any resources or documentation I can refer to for troubleshooting? Because I’ve tried to solving this myself but I can’t find specific guidance I need.

I suspect the nodes on the outer contour have different segments of lines and curves. Go into point mode and take a closer look.
