My Ultralight font started showing up in Indesign as Regular today when I generated a new version, and I don’t know why. This is driving me crazy, but from everything I’ve read it seems like it should show up as Ultralight. It shows up just fine in TextEdit.
Here’s the font info and OT info in FLAB (h-scrolling keeps it readable)
And here’s what I get in Indesign and other Adobe apps.
