Grayed thumbnails in glyphs, why?!

Hello,
My font window in Glyphs highlights some letters with a gray color as if there is no vector in the glyph, while there is (b, c, k, u in the image) It's not causing any problem (at least so far) but I'm wondering why it's happening. 

I'm relatively new to Glyphs, so apologies if it's a basic question! 
Thank you!

  • That's not what the grey background means, otherwise /K for example would have to have it too. My guess is that it marks the glyphs that have been changed since the last save, or something similar.
  • It's correct: As mentioned above, the grey background marks glyphs which were changed since you have last saved. You'll see the background disappear when saving.

    "a gray color as if there is no vector in the glyph"

    Well from your image, K L M etc. don't have vectors and they don't have a grey background. As said above, it shows glyphs that were modified so I assume you did some kind of changes to the glyphs on the bottom rows (even though they are empty, as soon as you make a change it will highlight the glyph, unless you undo all changes).
  • Thank you guys, that's right :)
    I just created those number and punctuation glyphs and that's why they were gray.
