Hey Hotari!
Thanks for flagging this! This looks buggy, but I can’t replicate on my end 🤔
Is it happening on browser, desktop app or both? Can you try to refresh your tab, and try to add once again the labels?
If this doesn’t help, please reach out directly to the support with a quick video recording and a copy of your file here.
This will help us to replicate on our end. Be sure to use the email associated with your Figma account, a link to the file, and share the file with support-share@figma.com (with edit access), so they can take a closer look. Thank you!
