Learning Lab: "Fixing your Pull Request"

Here is my pull request: https://github.com/shoemoo/github-slideshow/pull/3

The bot is telling me that there is a problem with the file name but I’ve edited it and it seems fine. Can anyone confirm?

I’ve restarted the course as per the advice from here: I don't know in "Fixing your pull request" but I’m still facing the same issue.

Anyone have any idea on how to get past this?
