Repository admin is able to delete the repository

As i understand from reading:

https://confluence.atlassian.com/display/BITBUCKET/Add+Users,+Set+Permissions,+and+Review+Account+Plans

and

https://confluence.atlassian.com/display/BITBUCKET/Delete+a+repository

Only repository owners should be allowed to delete it, but i deleted several repositories from this account only being granted admin access to them.
