The file converted from Fontlap7 to Glyphs does not show any strokes in the preview of Glyphs3.
There is a path in EditView, but in the preview, the path appears to be partially missing.
It looks normal in Glyphs2, and it looks normal when exported to OTF.
How can I make it look normal in Glyphs3’s preview window?
The path direction is wrong. Revert all paths (from the context menu).
