Non existent labels randomly appearing on issues

[bryanpedini]

• Gitea version (or commit ref): 1.7.5
• Git version: 2.17.1
• Operating system: Ubuntu Bionic Server 18.04.2 LTS
• Database:
  • PostgreSQL
  • MySQL
  • MSSQL
  • SQLite
• Can you reproduce the bug at https://try.gitea.io:
  • Yes
  • No: https://try.gitea.io/bryanpedini/test-repo
    However the bug is present here, since I did not created the "help wanted" nor the "todo" labels.
  • Not relevant
• Log gist: what is this?

Description

As title summarizes, in one of my issues (actually the one I created for testing purposes), some labels that I never created randomly appeared...
Bug confirmed on my server even after logging out, and even on a never logged in device.

After the link I provided on my own server is checked and confirmed (at least on 1.7.5), I will try (if suggested by Gitea devs) to update to the latest stable release to see if those non existent labels vanish as by magic...

Screenshots

(see above link for reference), however:
