Glyphs deletes layers when exporting/saving a .UFO

Hi, maybe this has been resolved in an other topic but nevertheless,
I’m working with Glyphs files and UFO workflow, and when I export a Glyphs file into UFOs straight from Glyphs it deletes my layers, whereas when I use glyphs2ufo it keeps the layers in place, but strangely it corrupts the feature file, anyway. Does anyone has any guess about it?
Thanks in advance!

Can you send me a test file?

it’s in your inbox, thanks again!
