I have multiple custom fonts uploaded on a new blank project, each with different weights. I am able to select 3-4 of them which appear in the weight list but the others are greyed out.
I have tried to find answers from other users reported issues but there does not seem to be an answer. I have tried removing these fonts and reuploading, to no-avail.
What service are you using to import the fonts (Google Fonts or Adobe Fonts)? Or is it a custom upload?
Usually this is the case whenever a certain font simply doesn’t have that weight available, or the weight you’re trying to select wasn’t selected upon the initial import of the font from it’s home service.
