Hi,
Please help me!
I would like to finish my actual project. This is a layered script font, with 8 styles.
Yesterday I tried to test under Windows 10.
After installing, the font preview under "Control Panel” show all styles look alike.
More precisely: Which style I installed for the first time, all the rest looks the same. 
(All 8 styles are guaranteed to be different.)
What can be the cause of a mistake?
Glyphs version: 2.5.2 - 1165
Thanks in advance.
Do you have special naming settings? Did you read the Naming tutorial?
Thank you, for quick answer.
I don’t think so. I don’t use custom parameters for naming.
Yes, even earlier. Because I tested under Windows 7, I got error. “Not valid fonts.”
After I changed to the shorter names.
Yesterday I came to Windows 10 testing. The installation was successful.
So far it seems, all 8 fonts working good under Windows 10.
But because the preview is wrong in “Control Panel/Fonts”, I think something is wrong.
All other installed font styles preview is good. I can’t figure out what is the problem.
This is interesting. I installed the Glyphs Sapperlot layered demo fonts.
I got same results. (I tested two different computers.)
What was it?
I added for each styles a different weight value.
weightClass you mean? Like 400, 500, 600, etc.?
Yes.
Could you send me some of the broken fonts? I need to have a look.
Yes. Which format? Glyphs or otf?
As OTF.
