Repository for organization

I am unable to create a new repository for my organization as the create repository button is dimmed out and no diagnostic messages are displayed to indicate that an error has been detected. The dialog accepted my proposed repository name and I added a brief description. I only asked for a .gitignore file to be created. Unfortunately, I have no screen dump as the dialog is too large to fit on the screen and cannot easily be dumped. The URL of the screen is https://github.com/organizations/clearcommunication/repositories/new

Did you choose a template for the gitignore? I think that’s the most common thing that gets overlooked on that page.
