Glyphs from components are not displayed in PDF

Hello there,

I have a problem with variable fonts.

Characters that I put together from components, such as the “ł”, are not displayed, (or rather the stems of the glyphs and the .noted character are displayed) when exporting a PDF from Adobe programmes when I have deactivated automatic alignment of the components.
As soon as I activate the automatic alignment in Glyphs or save the font styles as .otf, everything works fine. I have already created the glyphs manually as well as automatically by Glyphs.
Do you have an idea what’s going on?

So it work in on screen but not in a PDF? That sounds like a bug.
And changes behavior when automatic alignment is on or not? I can’t see how that would change anything. Can you send me the two font files?
