Missing kerning values in RTL Hebrew


I seem to have a problem with the kering values in Hebrew.

When I open a file created with Glyphs 2, in Glyphs 3 - all the kerning values are missing from the Hebrew glyphs, and the kerning groups are on the wrong side (Left kerning group becomes a right kerning group). The Latin glyphs’ kerning values remain the same.

The really weird thing is that when I export the fonts, and use them in Indesign - the Hebrew kerning is alive and kicking… even though the values are missing inside Glyphs.

Any ideas?
