Since no one is building on your repository, you can just make the changes and amend the commit:

    git add .
    git commit --amend

Then you can force push (typically bad, but since no one is using your fork it is ok). Assuming origin is pointed at your repo it would look like

    git push -f origin master

Note: typically it is best to create a branch for any work you do. So in your instance you would have wanted to create a branch named SEC-2002 to do all  your work on. If you read the contributor guidelines it talks about this and gives some links. I don't view this as critical, but some projects may be more strict about this than others. It certainly helps if you need to rebase (although if you know what you are doing you can still rebase with no problems)
