Sometimes you'll have a user who submits a pull request to your repository from a fork and no job will run under the account of the repo. This usually happens when the user is following the project fork on their personal account rather than the project itself on CircleCI. This will cause the jobs to trigger under the user's personal account.
In these cases have the user unfollow their fork of the project on CircleCI and follow the source project instead. This will trigger their jobs to run under the organization when they submit pull requests.
