Color Palette font not working

Hi I have working on Cairo font from google font to make Color Font with always black outline and inside color can change or Color Layer *, i have properly setup all layers but it’s not working, please help me here is link to my glyph file

As fare as I can see, the Color part is fine. but because of some other errors, Chrome and Safari do not load the color tables. Check fontbakery to fix those problems and see if that makes it work.

Apparently, when I save the file in Glyphs format, the color feature doesn’t work. However, if I edit it from a TTF or OTF file and export it right away, the color works as expected. But when I save it again as a .glyphs or .ufo file and export from there, the color feature stops working. I’m not entirely sure why, but this is the workflow that currently works for me.

Can you send me a .otf that works and one that doesn’t?
