Broken glyphs in variable font

I have this issue when I export my font as a GX-variation. A bunch of glyphs do not respond to the slider being dragged. When I export as an OTF the static version work just fine. The GX version also shows up fine in my Font Book as a preview. What am I doing wrong?

What version of Glyphs do you have?

Are you sure all glyphs are compatible?

I use version 2.4.4 All the glyphs show up just fine and interpolate normally. Just nog with the GX export.

Please update to 2.5b

I updated, but the issue is still there.

Can you send me the file?
