Unable to delete Custom Domain in Azure AD

Hey everyone, I'm trying to remove two custom domains from my Azure AD tenant and I keep getting a bad_request error when attempting to remove either of the addresses. Neither of these custom domain names are being used, they are NOT set as the primary domain, they are both .onmicrosoft.com addresses, neither are the initial domain, and both are passing pre-checks before failing to delete.

Any ideas?
