Hello @paata01,
We understand that this isn't how the EmojiOne glyph is supposed to work, and we apologize for any frustration this has caused. To troubleshoot the issue, could you please try installing the fonts shared in this link (https://github.com/adobe-fonts/emojione-color) and then relaunch Illustrator to see if it helps? Your response will help us identify the issue and provide the appropriate solution. Thank you for your patience, and we look forward to hearing back from you soon.
Thanks,
Anubhav
