Some metrics are out of sync

On a few glyphs I’m having on the top right corner, a Blue triangle symbol says: Some metrics are out of sync. What should I do in this case? On the same glyphs I’m also having on the left top order a Red mard says: The layers in this glyphs are not compatible. What does it mean and how can I fix it?


The Metrics warnings tells you that some of you metrics keys are out of sync. You can update them with Glyph menu > Update Metrics.

Thanks. I tried it but nothing is happening…

Do you have multiple masters? Then it might be in another master. If not, can you send me the file?

Thank you for your reply. Yes, I do have a few masters. I had to fix it manually. Thanks a lot for the help.
