Generate Instances labels all of them as Light

If I have a font with two masters (Reg 400, Bold 700) and two instances, one for each master, Generate Instances will create two new fonts. Although Font Info / Masters / Proportions / Weight for each new font will have the correct number (400, 700), they will both be labeled as Light. Glyphs 2.5b (1069).

Can you send me the file?

Will do. Seems that the Bold is actually OK, but the Regular instance is listed as a Light master. (2.9 KB)
