Exporting font with Glyphs Mini

Hi, I think my problem is simple to fix but I can not figure it out. I created different weights for the same font family, each weight is on a different file with a different name but when I export the font everything get read by the Mac Font book as ‘Regular’. This creates problem because they appear as ‘duplicates’ when imported in the system. Even if I rename the exported .otf the problem persists. Any idea? I must miss something…

Change the style name, at the top right in the Font Info.

And for testing, do not install in Font Book. Read here why:

Work perfectly, thanks
