Custom Parameter Export Glyphs not working in projects

Could it be that the custom parameter “Export Glyphs” is not working properly in projects? It works in normal glyph files. Using latest Glyphs version (909).

Thanks, L.

I just tried it and it did work. Can you send me your files?

You’re right, my fault. I did insert the values with commas, but should have done with line break. No it works.
However, I have the (non-exporting) Glyphs CR und .null in the font, and when I add the custom parameter “Keep Glyphs” then Glyphs gives a feature error.

Can you post the exact error message?
