I created a policy in Azure B2C, downloaded it and made some customizations. When I try to upload it I get these inheritance errors that I do not understand. I get the same error even if I don't make any changes and just try to upload the policy that I just downloaded. What is this error in reference to? Why is just not overwriting the policy with the uploaded policy?
