Problems Interpolating 3 axis, Letter Z

Hello Guys,
I trust you are well and safe. I am having problems interpolation the letter Z on two dimensions.
I’m working on a typeface which is interpolated according to width and weight.
My font file has 3 masters, a condensed bold, wide bold and a wide light.

All my glyphs interpolate properly except the letter Z ( please see attached screenshots)
any ideas on how to fix this? Any help would be highly appreciated slight_smile:


You need to draw you shapes like this:

Works! Thanks Bro!
