You have 2 commits incorrectly signed off. To fix, first ensure you have a local copy of your branch by [checking out the pull request locally via command line](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/checking-out-pull-requests-locally). Next, head to your local branch and run: ```bash git rebase HEAD~2 --signoff ``` Now your commits will have your sign off.
