I must admit that I am new to GitHub and not entirely sure how to use it properly. I have only ever cloned in the past. I tried to create a pull request but forked instead??

I think I have completed the issue that was raised. But maybe not how you intended. Please feel free to provide feedback as I would like to learn and improve.
