Issue with kerning export

Hi all,

I’m still quite new here and thank in advance for your help.

I’m trying to add some special characters to an existing font, but once exported with Glyphs, it doesn’t seems to export all kerning parameters which is required by the auto break line feature in my code. Even with the following scenario It doesn’t works:

-import of a font that was working with my auto break line feature
-export with Glyphs without changing anything on the font

I’ve already tried the following solution:
–> export in the kerning window (bottom left)
–> compress the kerning groups in the kerning window
–> delete all the kerning groups in the kerning window

but Its look like I’m missing something…
Thanks in advance!
