If a DNS zone is defined with a parent (not required) and you try to modify the name of that domain, the logic is not correct in determining if the new name is a duplicate or not. Bottom line, when using parents you may not be able to rename the zone.
This is likely to not be a huge issue as the use case in renaming a domain is fairly low.. you can always remove and re add it with the correct name.
