Hi @bluemurder Can you try:

1. In your local branch, run: git rebase HEAD~3 --signoff
2. Force push your changes to overwrite the branch: git push --force-with-lease origin patch-1

[bluemurder]

mm not sure why git gives me errors when trying to overwrite the branch: git push --force-with-lease origin patch-1. If needed I can close the pull request providing a new pull request with a single clean commit with correct signoff.

[beat-buesser]

Hi @bluemurder Ok, I agree closing and opening a new pull request might be easier.
