When saving fixtures including appgroup and appgroup_models and then loading those fixtures, we get the following error message:
django.db.utils.IntegrityError: Problem installing fixture '/Users/.../fixtures/admin_index_appgroup_models.json': Could not load admin_index.AppGroup_models(pk=9): UNIQUE constraint failed: admin_index_appgroup_models.appgroup_id, admin_index_appgroup_models.contenttypeproxy_id
However, when we then open the Admin portal, the app groups appears correctly. Any idea what might be going on?
