Point Git Gateway to different repo

I have had, for over a year now, had Netlify CMS working on a subdomain (admin.example.com). This edited files in a repo for the root domain (example.com). I have been using Git Gateway (on subdomain), which was pointing to the root domains repository. For some reason I was having trouble the token, when trying to work on it on localhost, so I disabled Git Gateway and re-enabled it. That fixed the issue with the token, but now it automatically sets the Git Gateway repo to the admin.example.com repo. I need it to point to the root domain’s repo, since that is where the content is

Even the documentation says that the repository field in Git Gateway is not editable. (A new limitation?)

Clear your localStorage, you will be asked to enter the admin url again.
