Unable to delete resources from root compartment

Summary:

I am unable to delete resources 0.10.in-addr.arpa and subnet0125.vcn0125.oraclevcn.com (both are CustomerDnsZone type)

Content (please ensure you mask any confidential information):

I see these resources in my Tenancy Explorer and I am unable to delete them. The tree dots menu is greyed out and when I select them both and try to delete via Actions menu I get "Won't be deleted-Delete action is not supported for this resource type."

In Resource Explorer both of those have links and drop down menu shows that they have OCIDs, however when I click on the resource link I get this error.
