Additional information

1. I think some of the warnings are about other apps (DjangoCMSForms, DjangoCMSFormsConfig).
2. I accept there may be a way for me to remove these errors in my project, without change to the repos in question, but I want to make sure there is not some root problem before I attempt this.
