Smart Component — What am I doing wrong?

I have two masters. I added to each of them a layer of slightly lower weight. For some reason, when I change the parameters the weight goes crazy as if it is sampling the shape from the wrong master. Any ideas what’s wrong?

I’m using Glyphs 3.0.4 (3097)


Can you send me the .glyphs file?

You called the axis “Weight” and that names is used for something else. Call it “Thickness” and it will work. And use 0–100 as axis range. -100–100 is not useful.
