I've connected Jira to my GitHub account but can't add any of my private repositories. My account is not part of any GitHub organizations. The GitHub configuration shows that it has access to 4 repositories:

However, when I go to add a code repository to a project, the pulldown is grayed out and shows a 🚫 icon.

I've tried revoking and re-granting permissions, reinstalling the app, and so on, but nothing has gotten me to the point of being able to add my private GitHub repository. Is there anything I can do fix this?
