Do any of these other fonts have OpenType Character Variants?
"Glyph Variants" could include a number of different OpenType features - which could appear there.
I could not find any documentation saying those applications support Character Variants.
Some applications do not support them.
InDesign does not.

Other OFL fonts which have many Character Variants:

• Charis SIL
• Junicode
• Source Code Pro
• Source Sans 3

All are available here in GitHub.

See if any of those work in your applications.
Meaning they display all the actual Character Variants.
