Export UFO problem

When I export masters to UFO, it only exports the Thin Master, no matter if I select all of them (3).
Everything is compatible.

I can’t find a simple way to export my masters to UFO.

Could you send us the .glyphs file? (to support at this domain)

i got the exact same problem. no matter which font i try.

newest beta, mavericks & lion

This will be fixed in the next beta.
